Everyone’s favorite oceanic candies have to be Swedish Fish and shark gummies! Use that to turn them into some unique under the sea party ideas. We love these ocean blue lemonade popsicles from Play Party Plan. They’re sure to be a refreshing treat on a hot summer day and as an added bonus, also have those tasty little gummies in the middle.

5. Step through kelp forests

One of the defining features of an under the sea party should be all the kelp and seaweed growing underwater. You can imitate them really easily by using metallic foil fringe curtains! This three pack of blue foil fringe from Amazon is a great option–they also come in green, so if you’re looking to recreate kelp that’s the way to go!

6. Turn your cupcakes into a school of fish

There are so many great under the sea party ideas that really get in touch with your creative side. The theme leaves so much room to play around and turn just about everything into a fun little detail. Look how cute these little fishy cupcakes from Two Sisters are! They leave room for custom cupcake toppers if you’re looking to include those as well.

We all know how much a photo booth can really make a big difference at a party. Giving everyone an opportunity to get some fun, themed pictures is a treat for both you and your guests. Order up a pack of fun underwater-themed photo booth props from Amazon to get started.

Then, you’re going to need a venue with a photo booth. That’s where Peerspace comes in handy. The platform offers you access to plenty of awesome venues that come with one ready-to-go. We love this Los Angeles home with a pool, hot tub, and a photo booth! It’s truly the ultimate party pad for any under the sea party.

8. Invite guests to your underwater kingdom with themed invitations

Getting everyone on board with your theme before the party is always the right move. Whether you’re sending invites digitally or through the mail, make sure they are clear about what the theme is. We recommend something like these editable under the sea birthday invites from Sugar Puff Kids on Etsy. They’re easily customized to your little mermaid’s name and clue your guests in on the type of party you’re having.

9. Have your snacks with themed dishes and cutlery
