Giant slugs are aggressive, evil level 9 mobiles, found in various locations around Arda. They have an acid attack that can damage equipment.

A giant slug is here, oozing around.

The thick, round body of the slug measures nearly three yards in length and is
totally covered in slime and ooze. Its colours range from a dirty green to a
light brown. The beast has left a trail of slime on the ground around it and 
its two thin eye-stalks keep searching the area for something or someone.
