Gecko (Tokay)

A loud, colorful lizard that can walk on ceilings/Small Animals

The tokay gecko is one of the largest gecko species and one of the loudest. Named for its distinctive "TO-kay!" call, it uses millions of microscopic hair-like setae on its toe pads to cling to nearly any surface via van der Waals forces. It has a notoriously strong bite for its size and a personality to match.
