Sluggy

Sluggies are hairy slug-like creatures found in Super Mario World 2: Yoshi's Island and its remake Yoshi's Island: Super Mario Advance 3. They come in two colors: pink with red spots and yellow with blue spots. Sluggies can fall on Yoshi from the ceilings. Sluggy the Unshaven is the boss form of a Sluggy. The only place they appear in is Sluggy The Unshaven's Fort. They can be defeated by jumping on them. They reappear in Yoshi's New Island in Ready, Steady, Go!, where they only come in red.
