Sea themed games for kids birthday party
Ring Toss
Turn this classic into an ocean adventure by using little plastic dolphins, sea stars, or even cones wrapped with seaweed-green streamers as the targets! Kids will have a blast aiming their rings and trying to “catch a fish” or “lasso a sea creature.”
Bean Bag Toss
Create or buy a bean bag toss board that looks like a big, open-mouthed shark or octopus! Little ones will love “feeding” their bean bags to the hungry sea creature. Bonus: it’s easy to play again and again without setup stress.
Dart Board Game
Look for a soft dartboard with fish, whales, or jellyfish targets—or DIY one with felt! Kids can take turns aiming their Velcro darts, trying to hit the big scores while imagining they’re underwater explorers tracking sea life.
Pin the Mouth on the Crab
This is a silly twist on “pin the tail” that little ones always love. Blindfold each player and see if they can give the crab its smile back. You can also try “Pin the Fin on the Shark” or “Pin the Pearl in the Oyster” if you want to switch it up!
Ocean Animals Dig Kit
This seashell excavation set is so cool—it’s like a mini treasure hunt! Kids can chip away at little bricks to reveal tiny ocean animals or shells hidden inside. It’s a calm, hands-on activity that’s perfect as a break between active games or a party favor station.
Pool Fishing Toy Game
This inflatable pool set turns any space into a fishing pond! Toss in floating fish, hand out the little rods or nets, and let kids fish away. Whether it’s in a water table, kiddie pool, or even a big storage bin filled with water—this one’s a hit with toddlers and preschoolers.
Ocean Bingo
Simple to set up, easy to love! Print off ocean-themed bingo cards with cute illustrations of sea creatures, shells, and submarines. Use goldfish crackers, blue gems, or stickers as markers. It’s the perfect calmer moment in between splashing and running around.
Seashell Painting Kit
Let the kids decorate real or faux seashells with paint, glitter glue, and stickers. Not only is it a relaxing craft, but it also doubles as a take-home keepsake that parents will actually want to keep.
Under the Sea Maze Books
Set out a little activity corner with maze or coloring books featuring fish, mermaids, or undersea treasure. It’s a quiet station that’s great for younger kids or any guests who might want a little chill time.
Ocean Animal Sticker Kit
Give each child a blank “ocean scene” (blue cardstock or printed backgrounds) and let them build their own underwater world using sticker sheets full of sea animals, plants, and bubbles. It’s fun, creative, and mess-free!
