The Best Mermaid Birthday Party Ideas For Girls

The classic games always seem to go over big at kid’s parties. This version of the famous Pin the Tail on the Donkey game from WERNNSAI features completing a mermaid’s tail. Kids take turns trying to pin the colorful tail ends on the mermaid, all while blindfolded. You get one 24 by 28 inch poster, a blindfold, and 24 reusable tail stickers. As a fun incentive, you can give prizes for first, second, and third place.

Think about Ariel in her grotto, surrounded by all of her treasures from the human world. That’s what this Pinterest user did when they came up with this fun mermaid party game. Fill a kiddie pool or sandbox with sand and hide a bunch of trinkets in it. You can put toy gems, jewelry items, and even quirky things like spoons, sunglasses, and other things that a mermaid might find fascinating. Give kids a toy shovel to start digging and find their treasures. You can also give them special cards with pictured items, so they have specific things to find.

Piñatas are always a winner at parties, especially since they’re filled with fun goodies. This cute mermaid piñata from Suilung is eye-catching with its vivid colors and whimsical style. But, if your birthday kid doesn’t feel right about taking a whack at a mermaid, you can find various other options. Look for giant seashells, jellyfish, or similar under-the-sea objects. If the party is for younger kids, consider using a pull-string piñata instead. These types are also a good option when you need to do the activity indoors.

Fill a large jar with goldfish or Swedish fish and give all the party guests a card to write their names and guess how many fish are in the jar. You can use printables and similar aids like these from DISTINCTIVS, or you can make your own. The person with the closest guess without going over wins. If anyone happens to get the exact number, you could have an extra special prize for them since it would be pretty amazing (and unlikely) if that happened.

Crafts and making jewelry are also some great ways to spend time at a party. And for a mermaid party, making jewelry is especially perfect. These necklace kits from FLYINGSEEDS make it easy to set up a craft station at your party for kids to create their own unique necklaces. To make things go smoothly, portion out materials beforehand so each child gets their own set of supplies. The great thing about this activity is kids can take home their necklace, so it also doubles as a party favor.

Kids won’t be able to resist digging into this sparkly, shimmering mermaid dip from About a Mom. It’s sweet and perfect for dipping cookies, featuring cream cheese, whipped topping, and more. If you’re feeling extra creative, bake up some mermaid-shaped sugar cookies to serve alongside the dip. You can select sprinkles that match your party colors, and you can even throw in a dash of edible glitter for some extra glitz.

Sandwiches are always a hit at kids’ parties because they’re easy to eat, and you can put different things on them to add instant variety to your menu. To match a simple sandwich to your mermaid theme, try these crab croissants from All That Glitters. All you need are toothpicks and large googly eyes; how simple is that? Serve up some turkey sandwiches, ham and cheese, grilled cheese, tuna fish, or whatever you want. You’ll end up with a tray of cute crabs that kids will love.

Sometimes, you can’t beat that perfect mix of sweet and salty. And that’s exactly what these tasty treats from Ever After in the Woods do. The giant pretzel sticks get an upgrade with white chocolate, food coloring, and of course, lots of sprinkles. Make them all the same, or create different colors; it’s up to you. You can easily alter the look by changing up the food coloring and sprinkles you use.

These clamshell cookies from MomDot are super cute and colorful. The best part is they’re also easy to make. You just need vanilla wafers, frosting, and large pearl sprinkles or Sixlets. Make the frosting yourself or buy premade frosting and portion it out to create different colors. This makes it incredibly easy to match this snack to your unique color scheme. Pipe frosting onto the cookies, and you’ll end up with a colorful sweet snack for your party food table.

A colorful bluish-green punch is a perfect fit for a mermaid-themed party. This Mermaid Lemonade from Jasper and Willow features, you guessed it, lemonade! But it gets its mermaid flair from a dash of food coloring, some vivid shades of sanding sugar, and colorful ice cubes. For an extra fun touch, get some fish-shaped ice cube molds and freeze cubes in different colors, so it looks like you have fish floating in your drink.

The great thing about cake toppers is you don’t have to be a master baker or cake artist to create a themed cake for your party. This cute cake topper pack from Ercadio features a precious mermaid and various sea creatures and other items that help you create an underwater scene on top of any cake. So bake your own masterpiece or buy one at your favorite bakery, then simply add a few embellishments for a festive and fun cake.

You’ve probably seen the famous doll cake at some point. You know the one, where the top half of a doll sticks out of their dress made of cake. This simple cake from Betty Crocker features a doll, but instead of putting it in the cake, it simply sits on top. If you’re on a budget, this is a great way to go, because the cake itself is relatively simple in terms of decorating. But once you add the doll, it really looks like a mermaid sitting atop her rock on the beach or in her grotto.

Here’s a more subtle take on a mermaid cake if you don’t want to go too big or too obvious. The piping work on this cake from Delish represents the scales on a mermaid’s tail. The key is to use bright colors (no matter which colors you choose) to present that magical, fanciful feel. If you want to add a bit more sparkle, finish it off with a dusting of edible glitter or sprinkles.

Love and Confections creates a stunning cake with beautiful piping work, bright colors, and tall layers. Two mermaid tails coming out of the top to make it look like they’re diving below the ocean’s surface. If you have mad piping skills but are unsure about your sculpting, this is a great way to create a DIY masterpiece. Once again, colors are easy to change, so you can go with the same idea and simply mix up different shades to fit your decor.

When you have a bunch of kids ready to eat cake, sometimes it’s just easier to skip the cutting. That’s why pull-apart cakes are such a great idea. This one from Dessert Now Dinner features a bunch of cupcakes that come together to form a beautiful mermaid’s tail. Frost them in any colors you’d like to match your party scheme, and add some edible glitter or sparkly sprinkles for added flair.
