Out of Bounds

Out of Bounds (OoB) is the area beyond the bounds of each course where there is no floor triangle underneath Mario. The game cancels any movement that would place the player OoB, and Mario will appear to collide with the boundary of the course. Some glitches can be used to allow the player to access OoB; this causes Mario to die instantly.

Colliding with the course boundary

When a movement into OoB is cancelled, Mario will appear to collide with the boundary of the course. This collision is different from those with walls: the player's angle is preserved (rather than reflected), and it is impossible to wall jump or kick off the course boundary. There is no way to preserve speed when a movement into OoB is cancelled.

Reaching OoB

Some glitches can be used to allow the player to reach OoB. So doing will instantly kill Mario.

• Recovering from a ledge grab into OoB.
• Forcing the the only floor below Mario (i.e. a floor triangle of an object) to become intangible.
• Chuckya can throw Mario into OoB.
• If the player reads a sign clone, Mario will move into OoB.
• Warping via teleporter clone
• Using a door from below the intended height.
