Cowabunga Candace is a online game on the Phineas and Ferb websites and is included in the "Phineas and Ferb Arcade" application for the iPhone iOS family. Candace wants to be to the surfing champion and impress Jeremy in the process. The game is based on the episode "Lawn Gnome Beach Party of Terror", and Candace is wearing a similar swimsuit in the game to the one she is wearing in the episode. The main aim of the game is to collect 50,000 points, which will earn you the gold trophy when you run out of tries.
Left makes Candace go to the left, right makes her go to the right, up makes her jump over obstacles and space makes her perform tricks (if she has collected any trick tokens).
There are 3 colored balls that string together to make a trick (e.g., log roll or method). If you collect all of them in a line, you will perform the trick corresponding with the balls (depending on their color).
Phineas, Ferb, Isabella, and Jeremy will show up at times, but will not interfere with the gameplay. If Jeremy is on-screen while Candace performs a trick, you will be awarded double the points (e.g., a 200 point trick becomes a 400 point trick if Jeremy is present). Trick tokens are placed randomly about the wave. Tricks are stored in the trick bar when collected , but only three can be held at a time. There are also obstacles that will hinder your performance. If you hit one, Candace will fall off her board and you will lose one of your three tries. If you hit an obstacle when you are out of tries, Isabella will appear and say "Rad surfing, Candace!", and Candace will reply "Yeah, I know." However this dialogue is not seen in the iPhone iOS version. At the end of the game, Jeremy will hand you a bronze, silver or gold trophy depending on your score. At this point, you will see Phineas, Ferb and Baljeet on Jeremy's side, and Isabella with some other people on Candace's side.
