Halfway through the first of the 30 levels, you meet Squeak and the full nature of the game starts. Squeak is a blue alien, who must also be guided through the levels. As he can't jump as high as you, he must sometimes be instructed to wait while you flick a switch or otherwise solve the puzzle of how to guide him through. If you stand on top of Squeak, you can be launched into an extra-high jump.
