Up'n'Down is an enemy from Mega Man 4. It is a small robot that jumps up and down from pits.
Up'n'Down returned in Make a Good Mega Man Level 2, where it appeared in the entries Forgotten Fortress, Joe Destruction Co., Escape Sequence, Beneath Sand and Rock, and The Stage Nobody Asked For, as well as the Wily stage Reality Core, the Tier X stages Nightwalk Castle and Deep Thoughts, the Pit of Pits sub-levels "da ba dee da ba di", "Up And Down", and "Water Test", and in Null and Void. Up'n'Down NPCs also inhabit Tier 1, though some are less accessible than others. It also appeared in the Make a Good Mega Man Level 3 Judge Application Level Space Crusade, and the Make a Good Mega Man Level: Episode Zero level Surfboard Showdown.
Up'n'Downs cannot be seen at first, but when Mega Man gets close, it will pop out from below, then slowly float back down.
By default, Up'n'Downs are red, but by setting "col = 1" in an Up'n'Down's creation code, it will turn blue.
