Sophia’s Little Mermaid Under the Sea 4th Birthday Party


A fun, non-traditional take on the Little Mermaid birthday party

Design Inspiration

Pinterest! I gathered tons of ideas and combined them all to put together this party.

Decorating Style

Lots of sparkles & glitter and shades of aqua, turquoise and lavender.

Project Details

The party took place at a local Spray Park. Instead of traditional party favors, the kids got to create their own sand bottles using colored sand. This was a hit!

I DIY'ed just about everything (except the beautiful cake and cupcakes) - Unfortunately, I ran out of time on party day and didn't get everything I had planned done in time for the party. 2 things that I really wish I could have completed in time were: the tails for the jelly fish balloons (I had 3-36" white balloons and purchased ribbon to attach to act as jelly fish tails - just ran out of time before the party started to attach them), as well as signs for the food, as I had fun names made up for all of the food: Sea Shell Pasta Salad, Peanut Butter & Jelly Fish Sandwiches, Seaweed Dip (spinach dip), etc. I was still happy with how everything turned out even though some items were missing :)

Ariel Doll Cake & Cupcakes: sweets (

Cake Table Banner: Handmade using scrapbook paper from Michael's

Party Plates & Napkins: Target

Headband: Baby Birdie Boutique on Etsy (

Princess Ariel Dress: Disney Store (

Favorite Items

I wish it would have photographed better, but I loved how the name banner on the cake table turned out - I'm not super crafty and it took me quite a while :)

I also really loved the clam cookies...and really just the entire sweet table! The cake & cupcakes really made the table.


Give yourself more time thank you think you would need to setup. I am notoriously late and that was no different on party day :)
