Party Themes

We recommend selecting a party theme that is age-appropriate for the majority of children in attendance.

Splish Splash Bash (Ages 1-3)

We’ll be splishing and splashing as we touch bumpy, prickly, and slippery ocean animals. Partygoers will use all their senses to explore the ocean’s seashore environment and make new discoveries as they take an imaginary trip to the beach. A visit to aquarium exhibits will surely be a hit for both parents and children. Join us and celebrate with a SPLASH!

All About Sharks (Ages 4-9)

These jaws deserve applause! Kids will get up close and personal with real live sharks, learn about what makes them the top ocean predators, and handle real shark jaws (teeth included!). Celebrate your next birthday with the sharks.

Sea-Fari Adventure (Ages 4-9)

Ready…set…explore!  Your birthday adventure begins with an interactive scavenger hunt and aquarium tour showcasing habitats such as kelp forests, tide pools, and coral reefs. At each stop follow clues and riddles to discover mystical seadragons, majestic sharks, and swirling fish.  A special live animal encounter will be revealed when the final clue is solved.
