CaillouQuest the Game is a fictional game made by Bubsy Bobcat. The only known scene in the game is of Caillou fighting Dora the Potioneer in her lair. The game also seems to have dimensional warp properties, as Caillou is able to traverse outside of the game world into the GoAnimate world, and make people enter the game world from the GoAnimate world.
It is unknown if this game is going to be released, since it is one of Bubsy's cheese-induced dreams, and therefore not likely to be real. However, Bubsy receives a file called "Caillou_Quest_v1.exe", indicating that the game may, in fact, be real.
