Jump N' Duck

Jump N' Duck is the video game that Buford brought over in the episode "Gaming the System" to show Phineas and Ferb. It is what inspired the boys to upgrade it.

Original Version
The game is a blue handheld game system that looks similar to a PSP. The whole purpose of the game is jumping and ducking. As an additional feature, you can take a picture of your face and put it on the character.

Updated Version
The game is set up like an RPG. You jump and duck your way through levels. Weapons include Candance's hairdryer, the health meter, and the camera on the original version. It consists of a screen and camera which projects you into the game. It offers five lives and has no cheat codes. Phineas and Ferb never took apart the original, they just built a new one
