Games for a Mermaid Party that will make a splash!

Mermaid parties are the perfect blend of imagination, color, and playful adventure. They give you a chance to transform an ordinary day into an enchanting under-the-sea world that kids absolutely love. From shimmering decorations to creative activities, everything about this theme invites wonder. But what truly brings a mermaid party to life are the activities — the games, crafts, dress-up moments, and interactive play that keeps little guests laughing, exploring, and fully immersed in the ocean-inspired magic.

Planning mermaid activities doesn’t have to be complicated. Some of the best ideas come from simple, child-friendly experiences that tap into pretend play and creativity. Think seashell toss games, coloring coral reefs, swimming and bubbles, or classic favorites with a mermaid twist like “Pin the Sea Star.” Add in dress-up elements like mermaid tails, sparkly crowns, pirate hats, and bubble necklaces, and kids become characters in your underwater story.

Check out these ideas for mermaid party activities…

One of the best parts of throwing a birthday party for kids, is the games and activities. I LOVE coming up with themed activities and stations for the kiddos to explore. It’s always my favorite place to work in little details and fun, quirky theme elements. My daughter’s mermaid party was no exception. Today, I’m sharing the fun stations we set up for her party…check it out.

Mermaid Games for a Party

Here are some clever themed games that will make your mermaid party even more fin-tastic! Don’t forget that simple games can be made to fit your theme with a little creativity!

Mermaid games bring energy, excitement, and playful movement into your celebration. Kids love games that feel like part of the under-the-sea world, and even classic activities become new again with a mermaid spin. Choose games that encourage laughter, teamwork, and imagination — things little guests naturally gravitate toward.

Try simple physical games like sea-creature races, wave-dance freeze, or treasure-collecting relays. You can also incorporate themed props, like soft foam fish, shells, or sparkly “treasure” gems to gather or toss. Mermaid games create instant engagement and help your party flow smoothly by giving kids a fun activity to focus on while waiting for food, transitioning between crafts, or just burning off excited party energy.

Games are also fantastic photo opportunities, capturing candid joy and movement that bring your mermaid theme to life. With just a few themed touches, your party becomes a lively underwater adventure.

Dress like a Mermaid or a Pirate

Dress-up is one of the most delightful parts of a mermaid celebration. Whether kids choose to become shimmering mermaids or brave ocean pirates, dressing up encourages imaginative play and helps every child feel like part of the story. You don’t need elaborate costumes — just a mix of simple, themed pieces.

Provide sparkly skirts, lightweight tails, glitter headbands, and shell crowns for mermaids. Add pearl necklaces, sea-foam scarves, or shimmering capes to make the dress-up area feel magical. For pirates, offer bandanas, paper hats, felt eye patches, and faux treasure coins. These easy accessories give kids confidence to play pretend while adding color and personality to your party photos.

A dress-up station also gives guests something fun to do the moment they arrive, easing transitions and setting the tone for the celebration. Kids love transforming themselves — and dress-up is the perfect hands-on activity to spark imaginative fun.

The first station I set up for the party was the dress up station. I love seeing all the little kids running around in outfits that match the theme.

I made some cute headbands for the girls with sea stars attached (tutorial coming soon!). The little girls paired these with mini lime green tutus that made them all look like cute little mermaids. The little boys got strips of fabric to wrap around their heads and Felt Pirate Eye Patches to make them feel like little pirates…aargh! This is a great way to make dressing up for a mermaid party fun for little boys too!

Pin the Sea star on the Mermaid

“Pin the Sea Star on the Mermaid” is a charming twist on a timeless party classic. Not only is it easy to set up, but it also fits beautifully into your mermaid theme without requiring complicated props. Simply create or print a large mermaid poster and cut out sea star shapes for kids to place.

Blindfold each participant, spin them lightly, and let the giggles begin as kids try their best to place the sea star in just the right spot. The fun comes from the unpredictability — the sea stars often end up on hair, elbows, or nowhere close at all, much to everyone’s amusement.

This game works well indoors, outdoors, or in small party spaces. It keeps kids engaged without requiring running or loud movement, making it perfect for younger mermaids or moments when you need a calmer activity. It’s sweet, simple, and always a crowd favorite.

This mermaid party game was super fun. I printed out the mermaid board large (size 16×20) and the kids took turns trying to stick the sea star stickers onto the mermaid’s hair. The printables for this mermaid party design (available for purchase at the bottom of this post) include these fun signs for playing as well!

Pin the “blank” on the “blank” is a simple game that can honestly be adapted to match ANY party theme. It’s always fun and makes for cute photo ops!

Make your own Mermaid Bubble Necklaces and Pirate Hats

Craft stations are wonderful for adding creativity to your mermaid celebration, and making bubble necklaces or pirate hats gives kids something memorable to take home. These activities encourage imagination and allow each guest to express their personality through their creations.

For mermaid bubble necklaces, set out colorful beads in sea-inspired hues like aqua, lavender, pearl, and coral. Provide stretchy cording and let kids design their own bubbly, treasure-worthy accessories. These necklaces become instant wearable art and perfect photo props.

For pirate hats, use paper templates or pre-cut shapes. Offer stickers, markers, foam shapes, faux jewels, and bold colors so kids can customize their pirate look. Add “gold” coins or skull-and-crossbone shapes for extra flair.

Crafts like these keep little hands busy, encourage creativity, and serve double-duty as favors kids will proudly show off.

The little mermaids made their own bubble necklaces. This was a HUGE hit with the little girls. They loved making their own mermaid jewelry.

We also didn’t want to leave out our cute little pirates, so we gave them the chance to make their own pirate hats and decorate them with stickers and jewels.

Seashell Toss

Seashell Toss is a simple yet delightful game that kids adore. It requires minimal setup but delivers big fun. Create “targets” by placing buckets, bowls, or decorated cardboard cutouts at different distances. Then give kids beanbags, faux seashells, or foam pieces to toss into the targets.

The game can be played casually for fun or structured with point values for older kids. It encourages hand-eye coordination while keeping the mood light and playful. Because it’s quieter and more contained than active racing games, it balances your activity lineup nicely.

You can theme your targets with ocean colors or mermaid motifs to maintain that magical under-the-sea feeling. Seashell Toss is easy, cute, and endlessly replayable — making it a must-have mermaid activity.

Using foam board and bean bags, I made a seashell toss game for the little quick fun competition game.

Coral Reef Coloring

Coloring stations are wonderful for kids who enjoy quieter activities or need a break between high-energy games. Coral Reef Coloring fits perfectly into a mermaid party, inviting children to create their own underwater scenes.

Set up a table with coloring pages featuring coral reefs, sea creatures, mermaids, and treasure chests. Add crayons, markers, gel pens, and even a sprinkle of glitter glue. Encourage kids to create unique worlds with bold colors, patterns, and imaginative details.

Coloring stations are flexible — kids can come and go, work individually or collaborate on a large shared mural. This activity also works well for younger guests or mixed-age groups. It’s peaceful, creative, and gives each child a keepsake they can proudly take home.

What mermaid party would be complete without a coral reef. On the block wall around the yard, the kids were able to create their own coral reef with sidewalk chalk. This was definitely a favorite as well!!

Swimming and Bubbles

If you’re hosting your mermaid party outdoors or near water, swimming and bubbles become instant, joyful activities. Water play perfectly complements the mermaid theme, allowing little guests to glide, float, splash, and pretend to swim like magical sea creatures.

Even if you don’t have access to a full pool, sprinklers, splash pads, inflatable pools, or simple water tables can create a fun and refreshing experience. Add bubble machines or bubble wands to turn your space into a sparkling sea of shimmering bubbles.

Kids love the sensory fun of chasing bubbles, popping them, and watching them float overhead. Swimming and bubble play combine movement with wonder, creating exhilarating moments that keep the party atmosphere playful and bright.

So of course, the best activity for a mermaid party is swimming. We decided to take our swimming to the next level with a Bubble Machine as well.

Splishing and Splashing around in the pool and chasing the bubbles was definitely the highlight of the mermaid fun!

Mermaid Party Favor Ideas

Mermaid party favors are the perfect way to extend the magic of your celebration. Offer items that reflect your theme and tie back to the party’s colors and activities. Think sparkly shell bracelets, beaded bubble necklaces, ocean-colored slime, mini mermaid dolls, sea creature stickers, or themed notepads.

Favors don’t have to be expensive — they simply need to feel fun and thoughtful. Packaging them in iridescent bags, pastel boxes, or mini treasure chests adds another layer of enchantment. Attach a cute tag with a message like “Thanks for making a splash!” to make them even more special.

When favors connect to games or crafts completed during the party, kids head home with both excitement and a reminder of the fun they had. They’re the perfect finishing touch for a memorable mermaid gathering.

Incorporating party favors into activities is a great way to stay on budget and still send your guests home with fun treats. Using items they make or get to wear during the party as favors is fun and efficient!

Beach Pail Party Favors

Beach pails make fantastic mermaid party favor containers because they’re useful, adorable, and totally on theme. Choose pails in ocean colors — aqua, pink, lavender, teal, coral — and fill them with small treasures that match your mermaid vibe.

You can include items like sand toys, bubbles, stickers, seashell bracelets, crayons, or small treats. Kids love having a bucket they can use again at the beach or sandbox, making it a practical and exciting take-home item.

Arrange the pails near the entrance or exit of your party, or place them at each child’s seat for a picture-perfect presentation. Beach pail party favors feel generous, fun, and playful — a beautiful continuation of your under-the-sea theme.

Last, but not least, were the fun party favors. Each child had a personalized beach pail with towels, googles, and fun mermaid themed candy and goodies…fin-tastic!!

Coordinating Mermaid Party Supplies

The easiest way to serve all the glorious party treats you make and buy is with some themed party ware. This is budget friendly and keeps the design flowing through every part of your party. Definitely a must buy!!!

For a mermaid party, themed party ware instantly elevates the entire celebration. Using coordinated plates, cups, napkins, and serving pieces helps unify your colors and details so everything feels intentional and magical. When your treats are placed on ocean-colored platters or shell-shaped trays, even simple snacks become part of the enchanting under-the-sea world you’re creating.

Themed party ware also takes the stress out of setup and cleanup. You don’t have to worry about mismatched pieces or digging through your cabinets for items that “might work.” Instead, your table looks cohesive from the moment you set it up, and cleaning afterward is quick and easy. This makes hosting more enjoyable and keeps your aesthetic polished.

Because mermaid parties are so visual, matching tableware helps your desserts, snacks, and drinks look extra beautiful. It ties everything together in a way that feels effortless, giving your party a coordinated, professional look without overspending or overscheduling. It’s one of the simplest ways to make your mermaid celebration feel truly special.

Choosing the right party supplies and tableware can also make a simple party into an extraordinary party!

Conclusion for Mermaid Party Games:

Mermaid parties are all about joy, sparkle, imagination, and the kind of magic that makes childhood feel unforgettable. When you bring together thoughtfully chosen activities, creative crafts, themed games, and playful dress-up elements, you transform your celebration from a simple birthday party into a fully immersive experience filled with laughter and wonder.

The beauty of mermaid party activities is how flexible and adaptable they are. Whether your gathering is indoors, outdoors, at a pool, or in a backyard, these ideas help you shape a celebration that flows naturally and keeps kids engaged from start to finish. Games like seashell toss and “Pin the Sea Star on the Mermaid” add movement and excitement, while quieter moments like coral reef coloring give guests the chance to slow down, recharge, and connect with their creative side.

Dress-up is often one of the biggest hits, allowing children to step into the roles of shimmering mermaids or adventurous pirates. These pretend-play moments spark imagination and help your theme come alive visually. Costumes, props, and accessories also add to the festive atmosphere and give you countless adorable photo ops.

Craft stations bring another layer of magic into your party. When kids create bubble necklaces, decorate pirate hats, or design their own gems and treasures, they aren’t just making something cute — they’re building memories, engaging in creativity, and taking home personalized keepsakes that remind them of the fun.

Water play and bubbles are perfect for warmer months and outdoor settings, offering refreshing, carefree fun that fits beautifully with the ocean theme. These activities help your celebration feel dynamic and joyful, giving kids the freedom to play naturally within the mermaid world you created.

And of course, themed favors — especially beautifully assembled beach pails — send little guests home with a final burst of happiness. Thoughtful favors help extend the magic beyond the party and show appreciation in a way kids instantly appreciate.

When these elements come together along with coordinated party ware, your mermaid celebration becomes cohesive, beautiful, and memorable. Activities keep kids entertained, dress-up sparks imagination, crafts fuel creativity, games add excitement, and favors close out the day with joy. These layers of fun help you create a celebration that feels detailed, thoughtful, and full of magic — the kind of party your child will remember fondly for years.

There are so many fun games and activities that you can include in your mermaid party to make it extra amazing. Turning ordinary party games into mermaid themed games is a great strategy! These ideas will inspire your party planning!
