Dan's pet/creature who usually follows him around. He possesses shape-shifting abilities and is able to transform himself into a mask which Dan used to hide his face from the public, becoming "Dunk Mask" before his identity was revealed. He is also able to turn into a set of head phones which Dan usually wears, or a face cover. Spanky also seems to have the ability to grow a new set of teeth at will when Dan used him as a can opener.
