Nobiiru

Nobiiru are slender, limbless enemies in Wario Land 3. They are situated in narrow passageways where Wario moves up. While they are in the walls, their eyes are visible. After that, they immediately extend with red bodies and protruding spikes, which stuns Wario if he touches them in this state. After a brief moment, they become white and their spike retracted, where Wario will bump off them if he touches them in this state. They will then retract back into the wall, repeating the process.

Nobiiru appear in the following levels, in the following quantities:
 * The Volcano’s Base (5)
 * The Grasslands (3)
 * The Big Bridge (4)
 * The East Crater (4)
