Marty is the green Thwomp seen in N64 Bowser's Castle immediately when the player enters the castle itself. It officially has no name, but fans liked him a lot and named him Marty. His name is edited using a program, cutting "MAR" of Mario, "T" of Toad and "Y" of Yoshi.
Theories to unlocking Marty
A lot of people like to speculate if Marty is an unlockable character. He isn't (only in hacked versions of the game). Theories include:
- Driving Bowser's Castle backwards.
- Power-slide turbo boosting (pressing R to jump while steering to the left or the right) around the Bowser Statue in the castle garden clockwise.
- Doing the same thing, but counterclockwise.
- Driving Bowser's Castle the other way around (impossible, because you can't drive up the stairs).
