The Underwater Expedition was mainly members only. The party item, the Heavy Hat, was in boxes at the Beach. Because it was heavy it tilted the whole island. Rookie was also meetable at the party with an all new background. At the Dock penguins could pick up the nine pieces of trash for a background. Members could go in the Maze. The final room, the Deep, had a Submarine Suit for them to get. If penguins lit up the 8 crystals in the room the conch shell would make a noise.
