Boing! (WarioWare, Inc.: Mega Microgame$!)
From the Super Mario Wiki, the Mario encyclopedia
There is a stick man bouncing off of a trampoline. The player must move the trampoline so that the man continues to bounce off of it, rather than hitting the ground. If the man stays in the air for about five seconds, the game will be won. However, if the man hits the ground, it will be lost. As the difficulty increases, the trampoline will get smaller.
