Under the Sea Birthday Party Invitations

Set the tone for your party right from the start by sending great invitations. You can either purchase pre-made invites or make your own. Here are some of our favorite invitation ideas for both options:

Use Ocean Theme Decals – This simple fish invitation was made by folding over a piece of blue cardstock and attaching colorful stickers and white paper with the party’s information printed on it. For a finishing touch it had two holes punched in the top and a coordinating ribbon threaded through.

Sea Creature Invitations — Write your party information on an invitationshaped like your favorite sea creature. A fish, a shell, or a starfish are all easy-to-make shapes that become fun backgrounds for your invite. Decorate your shaped invitation using themed stickers or your own artwork. Here are a few ideas for catchy invitation wording:

  • Come for a Whale of a Good Party Sure to Please You Heart and Sole.
  • An Under the Sea Birthday Party — Come Mussel in on the Fun!
  • Dive into the Fun at ____________’s Under the Sea Birthday!
  • You are O’Fishally Invited for a Whale of a Time!

 

** General Party Invitation Tips ** — If you choose to make your own invitations, don’t forget to include the date, location, and time of your party. It is also helpful to put the host’s name, RSVP by date, and either your phone number or email.

Under the Sea Decorations

Nautical 6'x23' Fishnet Blue
Decorative fishnet is great for an undersea party theme!
 

There are lots of great ways to decorate for an under the sea birthday party theme. Use shades of blues and greens, and add accents of either yellow, orange, or purple. Incorporate these colors into your décor by mixing them up in your tableware, and also by using them in things such as balloons and streamers, and you’ll be well on your way to a fishy feel. Here are some other ideas:

  • Stretch blue streamers close together to cover your ceiling, putting an occasional twist here and there in each one. This will look like the ocean is overhead!

 

 

  • Replace white light bulbs with blue bulbs for an underwater effect.

 

  • Tape colored streamers to your balloons to look like octopi legs.

 

  • Draw on smiley faces with Sharpie marker for a sea of floating octopi!

 

  • Cover your windows with blue cellophane and attach cut out shapes of sea life to create an underwater look.

 

  • Make an under the sea birthday party centerpiece by using glass bowls or containers filled with colored water (experiment with different shades of blue and green.)

 

  • Put sand and small shells in the bottom and floating candles on top.

 

  • If you have any pet fish, why not add their fishbowl to the arrangement! Accent with large shells.

Under the Sea Birthday Party Activities

under the sea birthday party game

  • Dig for Buried Treasure — If you have access to a sandbox, scatter small ocean toys, shells, plastic coins, and gems throughout. Give each child a sand pail and shovel and let them dig around for buried treasure. Little ones especially love this activity.

 

  • Crab Races — Have the children sit on the ground at the starting line. On the count of three, have them raise themselves belly up on their hands and feet and crabwalk backwards or sideways to the finish line.

 

  • Crab Soccer — Have the children get into their crab positions (belly up on their hands and feet) and play a game of crab soccer by using only their feet. (This works best with a lightweight ball.)

 

  • Flipper Relay — Divide the team into two groups for a relay race. Give each team a pair of swim flippers. Have the children take turns racing from point A to point B and back in their flippers. The first team with all its racers back wins. Make things even more challenging by having them carry a small bucket of water and seeing which team spills the least.

 

  • Sardines — This is a game of reverse hide and seek. Select one child to be “it”. Have that child find a good hiding spot while everyone else counts to 100. Then have everyone go look for the “it” child. As they find him, they should hide along with “it”. Slowly the party guests will disappear. The last child still looking will be “it” in the next game.

Under the Sea Birthday Party Food

Here are a few “sea food” ideas for snacks and drinks at an under the sea birthday party:

 

  • Sea Animal Shaped Sandwiches Use ocean cookie cutters to create ocean sandwiches (peanut butter and jelly or tuna salad work well for this.) You could also use the newly available goldfish shaped bread from Pepperidge Farms — what could be easier!

 

  • Submarine Sandwich — Order a large sub sandwich from your local deli. Stick a flexible straw in the top for a periscope and use mayonnaise or other sandwich spread to adhere sliced olives to the sides for portholes.

 

  • Put out bowls of Goldfish Crackers

 

  • Egg Boats — Make deviled eggs, and then cut pieces of cheddar or American cheese into triangular shapes, thread them through toothpicks, and stick one in each egg to make a boat sail.

 

  • Fishie Cubes — The day before your party, place one fish shaped fruit candy into each compartment of an ice cube tray. Fill with water and freeze overnight to make floating fishie cubes for your drinks.

 

  • Deep Blue Sea Drink — Make a blue drink by mixing lemonade or apple juice with a little seltzer and adding a few drops of blue food coloring.

 

  • Shark Cupcakes — Bake your favorite flavor cupcake. While they are cooling, mix vanilla frosting with a few drops of blue food coloring in a small bowl to make ocean icing. Finally, cut a candy wafer in half or cut a wedge from a gummy candy to form a dorsal fin. Stick it into the middle of your cupcake.
