Kids Party Themes – Mermaid Birthday Party


Mermaid Birthday Party Cakes

The hubs thinks I am insane.

Three birthday cakes for the Princess turning 5.

Seems totally logical to me:

1 – Her party with friends
2 – Her party at home
3 – Her party at school

The Princess Cupcake requested a mermaid theme for her school birthday party, so that’s what she got. She specifically did NOT want Ariel (peculiar for her, but okay…) so we went with generic mermaid. Actually, I like it much better. My kid has good taste.

Mermaid cke detailsI ordered the party supplies and made a chocolate cake because, “Jack likes chocolate.” Why we care what Jack wants for HER birthday, I’m not entirely sure but I suspect he was the boyfriend du jour that week.

All in all, turned out pretty cute.


Mermaid party ballons

I am pretty sure the request may have been inspired by a recent mermaid birthday party we attended. Super cute idea to fill the room with balloons as the “ocean,”

Mermaid party tails… and the mom even made adorable mermaid tales for each of the girls from bath towels, and had leis and shell necklaces for them to wear.


Since the party I have found the Cupcake wearing her mermaid tail while playing in her room on more than one occasion – the true sign of a great party favor!

Seaside and Beach Themed Cupcakes


beach themed cupcakesYou could even throw in some beach-themed cupcakes. We — and yes, I mean WE… (She was highly involved.) WE made these for a Memorial Day Splash party but they’d be just as cute for a mermaid party.

If you like the mermaid idea (sans our beloved Ariel) you’re in luck. Due to a — shall we say — “issue,” with the company I ordered from, we received excessive party supply extras which I now have on eBay for sale. If you’d like a Mermaid party in a box for a steal, here’s the listing on eBay.

And because I’m all about making things easier, I’ll even offer to make an edible image for you like the one on the top of our cake with your little girl’s name on it for a small fee plus shipping. Email me for details at trista (at) mommyupgrade (dot) com.


  1. There are really so many great ideas for birthday parties here but I can not find in here anywhere where someone suggests to invite a character or princess to any of these parties! I would think tjis would be the first thing considered in a dynamic, super fun party! With my girls here in the south that’s all the little girls rave about. Which princess can come to my party! There is a wonderful company down here in Atlanta called Look-alikes and Characters Entertainment. We have used them 3 years in a row and they never disappoint! The princesses are always young, gorgeous and talented! They also hold Tea Parties once a month at Historic Bulloch Hall in Roswell Ga and we go each month for a different theme. On May 7, 2016 they are holding a Grandmother, Mommy and Me Tea Party to celebrate Moms! My mother, myself and my daughter can not wait to go!

    • That’s a great idea — and I totally agree. We had a character featured at our recent Harry Potter party: Professor Sprout and her mandrakes came for potions class!
