This stage consists of a box with balls in it, capable of crushing the monkey through the walls resulting in a fall out. The box in which the balls are is constantly moving in a certain pattern that can impede the monkey's progress, as the monkey will usually be thrown around the box if you don't control correctly. The balls are also constantly bouncing off the walls and into each other rather quickly, so they can often collide with the monkey out of nowhere if you're not observing carefully.
To get to the goal, roll into the box. Try as hard as possible to avoid being knocked around by the balls. Move with your judgement as well as you can to roll into the goal. However, if you miss, you can try this same process again.
- This stage, along with Teapot, are the only stages in Super Monkey Ball 2 with a time limit of 30 seconds.
