Ideas for a Little Mermaid Party

Mermaid Party: Aubrey’s Little Mermaid Party.  For my daughter’s 5th birthday this year we threw a fin-tastic under the sea mermaid party.  Fun shades of purple, teal and green turn this ocean themed party into a beautiful mermaid themed party experience!

Welcome to Mermaid Cove!  For Aubrey’s fifth birthday party, we really wanted to make a splash with some fun under the sea.  

☑️ This Mermaid Party Kit is the perfect set to get your party planning headed in the right direction!


Aubrey loves mermaids, so for her birthday it was only fitting to have a mermaid party with fun little mermaids made to look like Aubrey.

The colors were lavender, aqua and green with lots of sand and yummy goodies.


Little Mermaid Party Decorations

We transformed the house and yard into a beautiful mermaid cove with bubble balloons, seaweed (streamers sewn to make them ruffle), and tons of floating jellyfish.  

The printables were designed with pretty shells, mermaids, and bright under the sea colors to accent the ocean floor of sand and seaweed covering the tables.

The entry was lined with bubbles (balloons) welcoming each guest into mermaid cove where they could dress like a mermaid or a pirate and join the underwater fun.

I made jellyfish out of paper lanterns and plastic tablecloths.  Wanna make these? Check out this jellyfish tutorial.


I covered the top of the backdrop with paper starbursts.


Food items were displayed on wood trays to accent the beach-y color scheme.

I also used brown sugar in all the plates to display the cookies and treats so it looked like sand.  This was awesome and the kiddos loved it!!

Sea stars on ribbon were throughout the party as accents.  I love the texture on these stars.


For the entry way, we decorated with balloons and a fun fabric covered wreath.  The wreath was accented with the printable welcome sign.

This simple foam wreath was wrapped in fabric strips and decorated to match the party.  For more welcome wreath ideas…check out this post.


The guests were all able to make their own bubblegum necklaces or pirate hats for the boys, play sea shell bean bag toss, pin the starfish on the mermaid, chase bubbles and swim in the mermaid lagoon.

Check out all the details of the mermaid party activities. It was a fun time under the sea.


Foam board cut out waves made a great photo op!


Mermaid Party Food Ideas

The little mermaids ate freshwater and saltwater cupcakes topped with cute fondant toppers made by Edible Details.


Some cupcakes were also topped with printable cupcake toppers.

Here is a close-up of one of the cute fondant cupcake toppers!

They also had Sea Star and Oyster Pearl cake pops from Nikki’s Cake Pops.




Adorable Shell and Mermaid cookies were served from Crafted Cookies and Sugared Hearts Bakery.



Another treat was Lavender Macarons from Splendid Sweet Shoppe.  

The cake was homemade and featured fondant waves and a brown sugar beach top complete with fabulous ocean themed fondant letters by Edible Details.  


For the cake, I made a simple 9×13 chocolate cake which is frosted in white cream cheese frosting.  I cut green and blue fondant into waves and wrapped around the cake. 

I then topped it with brown sugar to look like sand.  Lastly, I surrounded the fondant with glass candy.

The mermaids also had many non sweet treats including finger sandwiches, veggies and fruit.


To drink we served delicious Blueberry Le-mermaid.


Fish Rice Krispies Treats Tutorial

There were also chocolate dipped rice kripsies treats that look like under the sea fish bowls.

I made cute fish rice krispy treats.  I cut the rice krispies with a round cookie cutter, dipped in blue chocolate and added a cute candy fish and round sprinkles.  Easy, yummy and fun!!


Mermaid Dress-up Ideas

For the party, the girls wore skirts made by Ross and Rosie.  They also had necklaces made by Little Miss Petals.

I made headbands for the girls with teal flowers and sea stars as well.  


They also had lime tutus to wear over their bathing suits! 

I can’t believe my little baby is 5 years old!!! I love this little mermaid so much!! Thanks to all who helped make her day special!!
