Summer is upon us and it’s the perfect season to delight your boy or girl with a colorful, whimsical underwater “under the sea” birthday party! Marine life is strange, exciting and fascinating, and makes for a fun, creative, and interactive party theme. With some great ideas, a dash of creativity, and a bit of preparation, you can pull off your own unforgettable Under the Sea themed Birthday Party for your kids with ease.
Creative ideas for ocean-themed party snacks
Transform traditional party snacks into exciting, underwater treats with some simple creative ideas. You can serve both indulgent birthday goodies like cake and sweets, and healthy snacks disguised as exotic and exciting ocean nibbles. Here are some easy party snack ideas that are both fun to make, and budget-friendly:
Mini-aquarium Jello Cups :
Easy to make and very pretty, these individual cups of blue jello make great party favors. Pop a sea-creature gummy candy inside and some white sprinkles on top as seafoam for a unique finishing touch.
Shark Bait and Fish Food
Fill some clean plastic sandcastle buckets with snacks such as pretzels, little chocolates, cubes of fruit, gummy worms, crisps, or popcorn, and use plastic spades or (new) aquarium nets for serving. Label the buckets “shark bait” and “fish food” for extra authenticity.
Sugary Seaweed Strands
Bunches of green apple and red licorice make fun “seaweed” snacks, and they look great when presented in clear glass jars. An alternative, healthier “seaweed” snack is a skewer stick of green or black grapes, arranged together to look like seaweed strands.
“Under the Sea” Birthday Cake Ideas
Create a beautiful centerpiece for your Under the Sea party with the perfect ocean-themed cake.
Cutaway cake with secret underwater world
Start by making a simple sponge cake, finished off with blue icing or fondant. Cut into your finished cake, removing about ⅕ of the cake, and decorate the empty space as if it’s a window into an aquarium. Use cinnamon sugar as beach sand!
Tiered cake with each tier decorated as a deeper section of the ocean
The top level can be decorated with fondant molded into a whale, seal, or mermaid as a cake topper, the second tier with fish and bubbles, and the last tier with seashells, crabs, and seaweed.
DIY Underwater Wonderland Decor
Set the scene for your underwater wonderland with some ocean basics – bubbles, seaweed, and ocean creatures! Even if you’re on a budget, you can still create some great DIY decorations without too much time and effort.
Balloon Bubble Streams
Make a stream of bubbles by tying helium balloons to the string of one main helium balloon, so that the “bubbles” sit one above the other. Use dark and light blue balloons, with the occasional white balloon, and add a sea-creature balloon if you like! You could also use long balloons as coral – simply tie a bunch of long hot pink, yellow, and orange balloons together and set them on the floor.
Green tissue paper strips can be used as seaweed decorations. Hang them from tables, keeping them in place with rocks or big stones, and from door frames. Pipe cleaners can also be used to create little seaweed strands or bits of coral.
Under the sea party games
Keeping the little ones entertained at a birthday party can be a daunting task, but you can organize a few simple games that are both age-appropriate and fun to play.
Feed The Shark Toss Game
The game aims to throw a ball/bean bag through the gaping mouth of a cardboard cutout shark! Little guests will enjoy the physical aspect of this game, and it will expend some of their excess energy.
This game is super easy to set up. You’ll need a few wooden dowels (sticks), some string, and magnets to make the fishing rods, and paper fish with metal paper clips attached to them. The game aims to “catch” fish, and earn points based on the kind of fish you catch.
There are many more possibilities for creativity with this theme – if you can make it work, go for it! Your birthday boy or girl will love their fascinating, otherworldly underwater birthday party and remember it for years to come.
