Speaking of any celebrations, we avoid to see anything basic, especially when it comes to kid’s birthday party. By unusual, I mean something that isn’t typical Disney theme, but rather something like what’s in this page or Watercolor Under the Sea, Enchanting Under the Sea and Sea-lebration Under the Sea Under the Sea birthday invitation templates.

Splashy Decor That Won’t Sink Your Budget
Now, let’s talk about decor — because what’s a Under the Sea Extravaganza without a splash of style? When you’re throwing an underwater-themed party, you’ve got to make the space look like it was transformed by Neptune himself. But that doesn’t mean you have to drain your savings faster than water drains from a kiddie pool. There are so many easy (and budget-friendly) ways to make your space feel like an undersea wonderland.
DIY Under the Sea Magic
The best part of any Under the Sea Extravaganza is the creativity you can pour into it. Start with tissue paper seaweed — it’s as easy as crumpling strips of green paper and taping them to the walls. Add a few balloons in varying shades of blue for “bubbles,” and bam! Your house is starting to look like the set of The Little Under the Sea.

Now, let’s not forget about the jellyfish — and no, I don’t mean the kind that stings! You can create beautiful, whimsical jellyfish decorations by attaching paper lanterns to strands of ribbon or streamers. Hang them from the ceiling, and watch as the little ones “ooh” and “aah” when they walk into the room.

Don’t underestimate the power of a well-placed shell, either. Collect shells from your last beach trip or pick some up from a local craft store. Lay them out on tables, use them to anchor balloons, or even spray paint them with glitter for that extra bit of shimmer.
Where to Make a Splash: Top Under the Sea Party Venues
So, where’s this fabulous party happening? If you’re like me and love the idea of a backyard bash, you’re in luck — transforming your backyard into an underwater world is easier than you think. But if home isn’t an option, don’t worry! There are plenty of places you can host your Under the Sea Extravaganza without breaking the bank.
The Backyard Transformation
Your backyard is the perfect blank canvas for creating an aquatic paradise. Hang some blue streamers or tulle from trees to make it look like water is flowing through the branches. Add in a few inflatable fish or DIY sea creatures, and suddenly you’ve got an under-the-sea adventure ready for the kiddos.

If you have a pool, even better! Throw in a few floaty toys, and your Under the Sea Extravaganza will basically plan itself. Don’t have a pool? No problem! You can still give off Under the Sea vibes by setting up a kiddie pool or sprinklers to keep the kids cool while they splash around.
Under the Sea Glam: How to Dress Like the Queen of the Sea
You didn’t think we’d forget about the outfits, did you? What’s a Under the Sea party without a few glittery tails and shimmering crowns? You don’t need to spend a fortune to look like a Under the Sea queen — and I’ve got a few tricks up my sleeve to make sure you and your little ones look absolutely fabulous.
DIY Under the Sea Costumes
Let’s start with the kids (because, let’s face it, they’re the real stars of the show)—they’re the ones who’ll have everyone in awe with their adorable sea creature transformations! Now, when it comes to creating a simple and budget-friendly Under the Sea costume, we’re talking about an outfit that’s as easy to pull together as a mermaid’s hair flip! All you need is a sparkly skirt, tutu or leggings (because every underwater adventurer needs a little shimmer, right?), a cute top, and some accessories that’ll make them look like they just swam out of a Disney movie. And the best part? You don’t need to break the bank for this one—just get creative with what you’ve got in your closet!

For the tail, grab a piece of fabric (think shiny or iridescent if you’ve got it!) and cut it into a tail shape. Don’t worry about it being perfect; we’re going for that charmingly homemade vibe—besides, it’ll just add to the fun! Then, add some elastic around the waist so your little one can shimmy into their tail like they’re preparing for the world’s cutest underwater performance. And if you want to go the extra mile (because we know you do), sprinkle a little glitter on the tail for that extra mermaid sparkle. Glitter makes everything better—except maybe for your vacuum cleaner, but that’s a small price to pay for the magic it brings.
Delicious Bites from the Deep
“Under the Sea-Themed Party Treats”
Now that we’ve got the invitations, decor, and venue locked down, it’s time to talk about one of the best parts of any party: the food! When planning a Under the Sea Extravaganza, you can’t just serve any old snacks. We’re talking Under the Sea-level deliciousness, with a splash of creativity that will make everyone swim back for seconds.
Under the Sea-Themed Snacks That Are (Almost) Too Cute to Eat
For an under-the-sea party, presentation is everything. Start with some fun, ocean-inspired treats that are as cute as they are tasty. Try creating “fish-scale” cupcakes by frosting them with a simple buttercream and using blue and green candy discs to mimic scales. Bonus points if you top them off with an edible Under the Sea tail made out of fondant!

Don’t forget about the little snacks that keep the kiddos happy between games. “Seaweed” chips (aka spinach or kale chips) are a fun, healthy option that fits the theme. You can also serve up some “clam” cookies by sandwiching a marshmallow between two vanilla wafers — just add a candy pearl in the middle for that authentic under-the-sea vibe.
Under the Sea Cake
Now, let’s talk cake. A big, fabulous Under the Sea cake may be on your wishlist, but it doesn’t have to come with a big, fabulous price tag. One trick I’ve learned is to buy a simple cake from your local bakery and then decorate it yourself. Grab some blue frosting, edible glitter, and Under the Sea toppers (available at any party store) to transform an ordinary cake into something truly magical.

If you want to get extra creative, consider a dessert bar. Set up a DIY station where the kids can decorate their own cupcakes or cookies with ocean-themed toppings like blue sprinkles, candy fish, and starfish-shaped gummies. It’s a great way to get everyone involved, and bonus: it doubles as an activity!
Under the Sea Games to Keep the Kids Swimming
What’s a Under the Sea Extravaganza without a splash of creativity? Sure, treasure hunts and splash pools are fun, but there’s one activity that always brings a little extra magic to the party: a Coloring Page Session! It’s the perfect way to let kids channel their inner artist while keeping things calm (because let’s face it, every parent loves a moment of quiet!).
Under-the-Sea Under the Sea Coloring Pages
Imagine a table filled with adorable Under the Sea-themed coloring pages, from majestic Under the Seas swimming gracefully to playful sea creatures like dolphins and starfish. The kids can sit down and bring these ocean scenes to life with their favorite colors — and trust me, there’s nothing cuter than seeing little ones so focused on coloring that they forget they’re at a party.

Pro tip: You can easily find free, printable Under the Sea coloring pages online, or, if you’re feeling crafty, make your own with simple sketches. Lay out a variety of markers, crayons, and even glitter pens (because what’s a Under the Sea without a little sparkle?), and let the kids dive into their creative zone.
Wrapping It Up
By now, you’re basically the queen of the seas when it comes to throwing the perfect Under the Sea. You’ve got the invitations, the decor, the games, and the yummy treats — all without draining your treasure chest! The most important part? Remember to enjoy the day as much as the kids. Under the Sea parties are magical, but the memories you make with your child are the real treasures that will last a lifetime. So, take a deep breath, flip your fins, and dive into the fun! Oh, and don’t forget to take plenty of pictures — because you’ll want to remember this splash-tacular day forever.
