The team out does themselves when they design a hollow aquarium sand sculpture for the Aquarium of the Pacific in Long Beach, California to help launch their new exhibit Ocean Science Center, a big world globe. They invite a new sculptor to help out and he defis gravity with his hollowed out 9 foot tall giant jellyfish. Rusty and Sue go scuba diving with all the fish in one of the tanks while the rest of the team play with sea lions and sea otters and swim with sand sharks.
