Dolphin Under the Sea Party

We love this twist on an Under the Sea Party! This Under the Sea Theme focuses on the dolphin – the birthday girl’s favorite!

The best outdoor parties need the best themes and a fun Under the Sea party seems like the perfect idea. There are so many fun and creative things you can do to bring this theme to life. Just like this party here, creativity in the decorations, party supplies, food, desserts, birthday cake, backdrop, and party favors are what sets this party apart from the rest. Since this party was a pool party, the kids were busy swimming like little fish under the sea! But if you’re looking for more fun, just incorporate some Under the Sea games and activities!

This super adorable Dolphin Under the Sea Party was planned for a lucky 7-year-old girl who loves everything about dolphins, sea creatures, swimming and the beach! Set in South Africa, she invited 15 of her closest friends for a fun Under the Sea pool party! Colors used throughout the event were inspired by the sea and included whites, aquas, pale blues and greens. The fun Under the Sea party printables were designed by Sunshine Parties and really set the tone for the whole event! The kids enjoyed swimming, playing and throwing beach balls!

Under the Sea Happy Birthday Banner

This outdoor Under the Sea Party was made extra special for the birthday girl. For the Under the Sea dessert table, blue fabric was draped as the backdrop, which matched the blue tablecloth. Hanging jellyfish pom poms and fish prints (which the birthday girl picked out) created interest, along with the beautiful birthday cake and all the delicious Under the Sea themed food and desserts. The jelly fish pom poms were a fun DIY idea inspired by Martha StewartSunshine Parties designed the most adorable Under the Sea happy birthday banner that hung behind the dessert table. See the full dolphin under the sea collection here. We love the time and thought that went into all of the details for this special Under the Sea party!
