Otis

A doll whom was once an imaginary friend to a child has became a little too real for anyone, tall and lanky in stature. It probably has a difficult time getting around, but has no problem bending in strange directions. Regardless, it's friendly... Most of the time.
Probably lures in children with its original form before growing on their fears and insecurities to look like a monster.
No one knows what lies under the mask.
