The Inner Tube was a form of transport in Club Penguin. Most commonly used in Sled Racing, it resembled a large, red, inflatable ring with metal or plastic handles on both sides. A similar item was used in Hydro Hopper when the player was not holding a wakeboard. In Club Penguin Island, Tubes are available for members to use at any time.
- When waiting for more players without a game upgrade in Sled Racing, your penguin could be seen sitting on an inner tube at the top of the Sled Run.
- The Ultimate Proto-Bot was made with inner tubes, along with other various items.
- Next to the Hydro Hopper at the Dock.
- At the Ski Village, at the bottom of the Ski Hill, since December 2012.
- At the Ski Village, outside the Sport Shop, until May 2010.
