In Pikmin 1, there is a rare and dangerous glitch that causes Beady Long Legs to leave its arena. This glitch is most likely to happen when you leave the arena without killing it. Pikmin and/or Olimar have to be left at the gate to the small arena. The creature will then try to attack these, possibly leaving the arena. Once outside of the barriers, it will continue to pursue you. If you now run to the island where the Libra is, the enemy may fall into the abyss bellow, causing the game to crash (the game will also crash if you do not kill it after it leaves the arena after a certain amount of time). This glitch can basically happen with any boss that is fought in an arena.
