Mystery Box

Mystery Box (World 6-3) is the 53rd level in Super Monkey Ball 651 and the 55th stage of Advanced (115th stage overall) in Community Level Pack v2.0 's Challenge Mode.

Description
The stage consists of a room with a huge pit in the middle. The player starts at the bottom. The goal rests on a steep bridge above the pit. There are two wormholes on opposite sides of the pit, and two wormholes facing opposite sides of the bridge. The wormholes at the bottom link to the wormholes on the upper platform. There are also two adjacent green goals resting on top of the walls of the room. The floor of the pit changes in a checkerboard pattern from blue to purple.

Goal Tutorial
To get the blue goal, enter one of the wormholes to get to the middle yellow section of the level. The ramp to the goal is too steep to climb normally, so head to the left or right and face one of the wormhole at the bottom. Drop down, go through the wormhole again and you'll be able to climb up the ramp and finish. Another way to complete this stage is to pick up speed by going up the green ramp as far as you can, then turning around, entering one wormhole, exiting one wormhole at the bottom, entering the other wormhole at the bottom, exiting out of the other wormhole at the top, and then repeating this process until you get just enough speed to make it to the top of the bridge and enter the goal.

To get the green goal, perform the stage with either of the two methods but instead of entering the blue goal, go around it and keep going through the wormholes in a linear fashion. You will have to steer around and over the blue goal to keep your speed. Eventually, you will have enough speed to launch off of the bridge, going over the blue goal, and getting a straight shot at the green goal.
