Anklebiter is a short, stubby monster who appears in the middle of the night. He looks for people who sleep with their toes out, so he can slurp and suck on them.

During the day, Anklebiter is nowhere to be seen. However, once the sun sets and people begin going to sleep, anklebiter materializes as a black, shadowy goop puddle, quickly taking his normal white and black banded form. He usually appears quite close to his target, often in the same room, in whichever corner is darkest.

Anklebiter's foot fetish is quite extreme, and what earned him his nickname. He also goes by Ankle, for short.

Anklebiter has a brother named Slink . The two sometimes work together
