CP Knowledge – Hydro Hopper

Welcome to the first post of the brand new series CP Knowledge. This is a series where I will talk about every single minigame on Club Penguin, starting today with Hydro Hopper. The posts will include how you play the game, its history, stamps, trivia, high scores, and a personal review of the game! Hope you enjoy it!


Hydro Hopper is a single-player game accessible through the Dock. The player rides along on an inflatable red ring, known as an inner tube, towed by a motorboat. The inner tube follows the mouse cursor in an arc, and the goal is to not tip over. There are nine different obstacles you have to avoid, if you hit one of them you tip over and lose one of your three lives. All obstacles, except the buoys, can be jumped over by clicking the left mouse button or space bar. Starting at level two you can earn extra lives by collecting a life ring. Although you can never have more than three extra lives

   Earning points is done by dodging or jumping over an obstacle. You get one point per dodged item and ten points for jumping over an item, so if possible you should always try to jump instead of steering away. When the game ends the player earns one coin per every ten points.

   Instead of an inner tube, members can buy a wakeboard from the Game Upgrades paper at the Dock. There are two different types, both cost 300 coins. The wakeboard was introduced on the 31st of August 2007 and was formerly bought in the Sport Shop, but was moved to its current location on the 27th of March 2009. Using a wakeboard in the original Club Penguin did not affect the gameplay other than aesthetics. In Club Penguin Rewritten and New Club Penguin having the wakeboard equipped lets the player stay in the air longer and grants double points for every over-jumped object.


Hydro Hopper is one of the five games that has been on Club Penguin from the absolute beginning. It is based on a previous game from Rsnail, the creator of Club Penguin, called Ballistic Biscuit. Ballistic Biscuit was created in Flash 4 and launched in early 2000, instead of penguins the characters were humans. Rsnail later made several different versions of the game for other websites, one of them being Club Penguin.


Hydro Hopper is a game that has never had stamps, although in September 2018 Club Penguin Rewritten administrator Joee confirmed that he wanted to add stamps to make it more exciting to play. However, he resigned in May 2020 and we still don’t know if there ever will be stamps for the game. 


There is no way to know if these scores are legit, but the highest recorded score I could find is this one by a penguin called xMBTx who managed to get 24737 points. Another great score by the same player is when xMBTx got 22775 points about a year later. One more example is when penguin Winkie4 once decided to record his Hydro Hopper round and got a whopping score of 20496 points. 

   However, none of these scores go by the principle that the score divided by ten equals the number of coins you get. So I must say I’m a little suspicious as to how they got more coins than they should have. There might be a way of doing so, and that I – and seemingly everyone that has made a post about the game on the internet – am just unaware of it. The only great score I could find where the number of points does equal the number of coins is this one, where penguin Jrp55 got 10560 points and 1056 coins.


  • Hydro Hopper is one of the least recommended games for earning coins and also one of the simplest games, arguably the simplest of them all.
  • The game becomes quite repetitive after level 8 as no new things get introduced. This makes the game one of the less popular ones.
  • The background music used is a song bought from Smart Sound called Yessir composed by Craig Riley. The song was also used for the game’s 2nd anniversary.
  • There is a Hydro Hopper Background which was available between May 4th and November 2nd, 2007. It was also available on Club Penguin rewritten between February 28th and June 6th, 2019, and then again between August 7th and November 12th, 2020.
  • According to the Rocketsnail Games website, there was going to be a sequel to this game, called Ballistic Biscuit 2.
  • It was the first game Rsnail ever made with Flash (good job!).
  • Hydro Hopper was originally called Ballistic Biscuit on Club Penguin too. It was renamed after a poll in issue 99 of the Club Penguin Times published on September 6th, 2007. The name Hydro Hopper won by a lot, with 49 percent of the votes compared to the second place’s Board Breaker with 26 %. The other three alternatives were Water Yachter, Water Caper, and Ballistic Boarder.
  • From level one to seven there are different messages shown between every level. From level eight and onwards the message becomes “Good job!”. 
  • Hydro Hopper measures your reflexes as you have to be quick to click if you want to survive.
  • There are unlimited levels in Hydro Hopper.


I would rate this game a solid 5.5 out of 10. It is simple and fun when you want to play something without plenty of thinking. I enjoy playing the game, but as I mentioned earlier it does get a bit repetitive after level eight. The jokes that are shown between levels are a great touch, but after you’ve played the game a certain amount of times you already know them. The game isn’t great for making a fortune, but with some practice, you can get a good score and earn quite a lot.

That’s all for me today, hope you enjoyed this new series! See ya next time!
