How to Throw an Under the Sea Theme Party | The Party Darling

Looking for ideas on How to Throw an Under the Sea Theme Party? We have some fun under the sea party supplies and ideas to share with you.


Start with a cute custom under the sea invitation to match the party theme and decor. We created an ocean-themed party invitation to match the under the sea birthday party supplies in our online shop. Just provide the details for your child's party and we will update and send you the digital file for you to have printed.

Create a whimsical ocean backdrop with this custom under the sea balloon garland in orange, yellow, blue, and pearl white. These bright and fun colors coordinate with this unique under the sea party theme.

Balloon garlands are so popular and add so much to the overall party decor. They are easy to make and do not require helium. Check out our blog post on how to create a simple balloon garland.

Transform your party into an underwater adventure with this under the sea banner. The banner features shiny colorful sea creatures such as fish, a shark, a whale, and jellyfish, as well as the words "under the sea." It is pre-strung to make for easy hanging. However, we chose to remove the die-cut sea creatures from the string and attach them to the wall using glue dots and then hung them under the balloon garland.

Make some waves at your buffet table with this under the sea tablecloth. This paper table cover features blue bubbles and wave accents and will help protect your furniture from nicks and spills.

Take a chomp on boring lunch tables by serving up snacks with shark snack platters. This blue foil paper tray shaped like a friendly grinning shark is perfect to put sliders on or pour a bag of chips onto for guests to enjoy.

Have a party on the ocean floor! Set the table with these under the sea plates with an array of sea creatures in bright and shiny colors. Add these adorable under the sea napkins featuring a yellow, black, and white striped tropical fish. Finish the table setting with coordinating Bermuda blue forks

These fin-tastic under the sea cups feature a shiny ocean blue background with colorful fish swimming around. Fill the cups with ocean water (blue punch) or use them to hold bite-sized snacks or craft supplies at your ocean-themed birthday party.
