Tilt-o-Tube is a multi-player mini-game in Club Penguin Island, added in the 1.5.0 update, that can be played at the Beacon Boardwalk. It is accessed from a buoy in the middle of the bay that transforms into the platform the game is played on every three minutes. Only members can play this game, and they must be riding a tube.
After the buoy transforms into a platform, a small trampoline between the platform and the row of icebergs at the south end of the boardwalk appears. Members can then interact with the trampoline to access the platform. After 30 seconds, the trampoline disappears and the game starts. Players have to bump into others on their tubes, trying to knock them off the platform, while trying not fall off themselves. However, the platform is constantly rotating and tilting during the game, and eventually shrinks in size as well. If a player falls off, they are out of the game. After all players fall off the platform, the game ends, and the platform rises out of the water and flies away. Players do not receive anything for success during the game, even if they are the last one on the platform.
