Tubes are a mode of transportation in Club Penguin Island that can only be used by members. Tubes can be used by pressing the action button for them in the bottom right corner of the game screen. Pressing the button causes the player to ride on the tube, and pressing it again dismounts the player from the tube. Tubes can be accessed through the inventory by clicking a green button with an Island Tube on it, on the bottom of the screen, next to the buttons for Gear and Party Supplies.
While riding a tube, the player slides along the ground and on top of water. Tubes are affected by friction, so if the player is standing still or moving slowly and mounts the tube, the tube will move slowly. If the player is moving quickly, jumps off of something, or is on a slope and mounts the tube, it will move faster.
Prior to the 1.2.0 update, only the Island Tube was available.
Tubes are an essential part of the Mt. Blizzard zone, and a tube/sled racing game is featured at its very peak.
