Snake is the 23rd Expert floor in Monkey Ball and Super Monkey Ball, and the 42nd Expert stage in Super Monkey Ball Deluxe. It also appears as the 152nd Ultimate stage with continues, and the 192nd without.
It begins on a small platform. The goal is opposite the player on an equally small platform. Between the goal and the platform is a path that (as the name suggests) moves in a wavy, snake-like motion.
To get to the goal, you just need to move along the sliding blocks as they form a straight line. Although they do move back and forth, they do so in a pattern, meaning there is always a relatively straight line of blocks to go on. You will have to change directions several times, so control your speed.
