Dive into an unforgettable adventure with an Under the Sea Party! Whether you’re hosting a kids' birthday bash, a summer pool party, or an ocean-inspired gathering, this theme offers endless possibilities for fun activities, sea-inspired decorations, and creative food ideas. With these tips, your Under the Sea Party will be an event everyone will remember. Let’s dive in!


Under the Sea Party Essentials


Under the Sea Party Invitations

  • Design Ideas: Create invitations shaped like seashells, fish, or underwater treasure maps. You can also design invites with ocean waves, coral reefs, and cute sea creatures like fish, turtles, and mermaids.

  • Sample Text: “Come explore the deep blue sea! Join us for an Under the Sea Party filled with fish, fun, and ocean-inspired adventures. Wear your beach gear and dive in!”


Pro Tip: Use online tools to design your own ocean-themed invitations, or purchase pre-made invitations with mermaids, sea stars, and sea creatures.


Under the Sea Party Decorations

Transform your venue into an underwater paradise with these oceanic decoration ideas:

  1. Color Scheme: Opt for shades of blue, teal, turquoise, coral, and sandy beige to mimic the ocean, with pops of bright colors for fish and sea creatures.

  2. Backdrops: Set up a shimmering underwater scene with blue and green streamers, fish cutouts, and seaweed. Create an ocean backdrop with bubble machines or fabric drapes.

  3. Balloons and Tableware: Use ocean-themed balloons, inflatable fish, and seashell decorations. Serve food and drinks with sea creature plates, cups, napkins, and tablecloths.

  4. Underwater Lighting: Hang string lights to create a soft, glowing effect like sunlight filtering through the water.

  5. Marine Life Decor: Add coral reef elements, fishnet hangings, and beach towels to give the space a coastal, aquatic look.


Under the Sea Costumes

Encourage guests to dress up as mermaids, pirates, sea creatures, or divers. Provide fun party hats or sea-themed accessories like fish tails, snorkels, and goggles as party favors for guests who aren’t in costume.


Under the Sea Party Activities

These activities will make your guests feel like they’re swimming with the fishes and exploring the depths of the ocean:


1. Ocean Scavenger Hunt

  • Hide small plastic sea creatures, shells, and other ocean-themed items around your venue. Create a treasure map or set of clues to guide your guests to these hidden treasures.

  • Pro Tip: Use glow-in-the-dark items for an exciting hunt after dark.

2. Make Your Own Fishy Craft

  • Set up a crafting station where guests can make their own ocean creatures using construction paper, googly eyes, glitter, and stickers. They can create fish, sea turtles, or octopuses to take home as party favors.

3. Underwater Obstacle Course

  • If you’re hosting the party outdoors or at a pool, set up an aquatic obstacle course with items like hula hoops, floaties, and inflatable pool toys. Kids can race through the course and complete different sea-themed challenges.

4. Fishy Relay Race

  • Set up a relay race where guests must swim or "sea creature crawl" across the room or yard, passing a “sea shell baton” to the next person in their team. Add challenges, such as hopping like a frog or balancing a ball like a sea turtle.

5. Pin the Tail on the Mermaid

  • A fun twist on the classic "Pin the Tail on the Donkey" game. Blindfold guests and have them try to pin a mermaid tail onto a large mermaid poster.


Under the Sea Party Food & Drinks

Seafood and ocean-inspired treats will make your party even more exciting:

  • Fish-Shaped Sandwiches: Use fish-shaped cookie cutters to make fun sandwiches with fillings like tuna salad, peanut butter, or deli meat.

  • Seafood Cups: Serve shrimp cocktail or crab dip in small cups, garnished with parsley and lemon wedges for a true undersea experience.

  • Ocean Jell-O Cups: Make blue Jell-O cups, layering them with whipped cream and gummy fish or sharks for an underwater dessert.

  • Mermaid Macarons: Serve macarons decorated like seashells, sea stars, or with blue and purple swirls to resemble ocean colors.

  • Starfish Sugar Cookies: Bake and decorate star-shaped sugar cookies to look like starfish, or use animal-shaped cookie cutters to create other ocean creatures.


Under the Sea Drinks:

  • Ocean Punch: Create a blue punch using lemonade, blue fruit punch, and a few scoops of sherbet for a bubbly, ocean-inspired drink.

  • Mermaid Lemonade: Serve up lemon-lime soda with a splash of blue food coloring and a decorative umbrella for a tropical mermaid drink.

  • Sea Foam Soda: Mix lemon-lime soda with coconut milk for a fizzy, creamy drink topped with a dollop of whipped cream.


Under the Sea Party Favors

Send guests home with ocean-inspired favors:


Under the Sea Party Games

Keep the party flowing with these aquatic-themed games:

1. Musical Sharks

  • Play a game of musical chairs with ocean-themed music (like “Under the Sea” from The Little Mermaid). Instead of chairs, use large beach towels or pool floaties for guests to sit on when the music stops.

2. Fishing for Prizes

  • Create a fishing game where guests “fish” for prizes using a fishing pole and magnetic fish. Write numbers or prize names on the fish, and let guests win small gifts.

3. Toss the Ring into the Fishbowl

  • Set up a game where guests throw plastic rings into a fishbowl or large container. The person with the most successful tosses wins a small prize.


Under the Sea Party Planning Tips

  • Timing: A 2-3 hour party duration works well for this theme, allowing time for games, activities, food, and socializing.

  • Budget-Friendly: You can find ocean-themed party supplies, decorations, and favors at affordable prices online or in party stores. DIY decorations like tissue paper jellyfish or paper plate fish can add a personal touch without breaking the bank.

  • Indoor or Outdoor: This theme works perfectly for both indoor and outdoor parties. If you're hosting at a pool, consider providing water toys like floaties, pool noodles, and beach balls. For an indoor party, create a “beach” area with sand, inflatable fish, and lots of tropical decor.


Conclusion: Dive Into the Ultimate Under the Sea Party

From ocean-inspired food and drinks to creative activities and decorations, this theme will keep your guests swimming in joy.
