Your party is as cute as can be with this collection of Under the Sea Party Supplies. Featuring a bubbly blue color palette, these birthday party supplies are great for your little swimmer. The matching cups, paper plates, and napkins feature a group of party hat-wearing ocean buddies against a bubbly background of balloons and streamers. Invite them on an underwater adventure with Under the Sea Invitations. These fish birthday invitations feature an adorable octopus. Want to take your invitations up a scale? We offer custom invitations and thank you notes for your under-the-sea birthday party! Next, it's time to decorate the party room for a celebration. Hang swirl decorations and a matching scene setter to make guests feel like they just traveled down under. Use the scene setter as a DIY photo background and take fun pictures of all the ocean explorers. Your little birthday swimmer will feel extra special when they see an ocean-themed birthday banner customized just for them! Round out your Under the Sea Party Supplies with complementary solid-color decorations, including paper lanterns, streamers, and of course fish balloons. Whether it's time for pizza or a slice of under-the-sea cake, we have a variety of plate and napkin sizes to suit your needs. You can put your own unique spin on the party by using both Under the Sea tableware and solid-color tableware for a one-of-a-kind, whale-done look. Don't forget to complete place settings with matching plastic forks, knives, and spoons! With disposable tableware, your cleanup will go swimmingly. Send the whole school of fish home with under-the-sea party favors. Fill favor cups and goodie bags with ocean-themed pencils, bubbles, sunglasses, and more. With a variety of temporary tattoos, wristbands, and masks to choose from, you can get them all dressed up for super cute underwater party photos. Browse our Under the Sea Party Supplies and ocean party decorations to inspire your under-the-sea party ideas!
