Hydro Hopper (formerly known as Ballistic Biscuit) is the first-ever game in Club Penguin. This is because it was not original, as it made its debut on the now-defunct Rocketsnail Games website, in which you played as a human. It is located at the Dock. In it, the player rides along on an inner tube, towed by a motorboat, and avoids obstacles in the water. Non-members can only use inner tubes during gameplay. Members can choose an inner tube, or a wakeboard to use during the game. After a while, players go on to the next level. In between the levels, there are tips, but after a few levels there are jokes instead, and after a few more, simply congratulatory messages.
Hydro Hopper first started off as Ballistic Biscuit, a game featured on many flash game websites. The first version (with only one level) only featured humans, however a revised version featured humans and a penguin, a reference to Experimental Penguins, a game also being developed by RocketSnail Games.
On and after August 31, 2007, you can buy and ride a wakeboard instead of inner tubes.
On September 6, 2007, a new name for Ballistic Biscuit was needed, and so through a poll in the newspaper, penguins could choose a new name. On September 21, 2007, Ballistic Biscuit was re-named Hydro Hopper.On March 27, 2009, a new catalog was placed next to the boat.
