Underground Bug for Super Mario Land 2 - Gameboy

• Underground Bug

Go to any long pipe going down in a level you've already passed, and go down it. While still in the pipe, pause and then press SELECT. Then, play any level you want. In most of the levels, Mario will fall through the ground and end up in a strange jumble. Don't hit any ? blocks or grab any coins there, or the game will freeze. Very strange and funny!
