Keyzer

Keyzer is a small ghost-like creature from Wario Land 4. It has a key for a nose. It will unlock the next level for Wario once obtained and taken to the exit. In the game's instruction booklet Wario states that Keyzer looks like a pushover and he could easily take him down. Keyzer appears in every level to unlock the door to the next area for Wario.

Wario's Description
''He looks like a pushover... Too bad he's not an enemy! I'm out here risking my life and he just sleeps all day! Hey! Keyzer! You'd better wake up and smell the coffee or I'm to smack you one real nice!!
