Bump is the first floor of Advanced in Monkey Ball, Super Monkey Ball, and Super Monkey Ball Deluxe. This floor is given a 1 out of 10 difficulty rating.
It is exactly the same as Plain, except the rail around the stage was replaced with a less effective one that allows the player to fall off and a bump in the middle of the stage.
To complete this stage, just go straight forward, or go around the goal for bananas, and then make it to the goal.
