Hydro Hopper

Hydro Hopper (formerly known as Ballistic Biscuit) is the first-ever game in Club Penguin, and was the original source of coins in the game. 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 the game, 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. According to Aunt Arctic, it is the oldest game in Club Penguin.

Tips

• If you jump, think of it as having temporary invincibility, except for Buoys.
• Remember to predict!
• Jump over obstacles to gain extra points! You get 10 points for every obstacle you jump (a special sound will be heard and the penguins on the boat will raise their flippers)
• If you lose a life, don't worry. Try to get the lifesavers! They usually appear only once at the beginning of the level.
• You get 1 point every millisecond you hover over an item. So ten if you jump one item by going straight over, for maximum points when multiple items, move the player left to right as quickly as possible. But you must be wary of buoys.
