Hisser

A Hisser is an Underland giant frill-necked lizard. When threatened, Hissers will first try to intimidate the other creature by showing off their multicolored frills, then by stomping the ground. If this does not work, the Hisser will run away and climb a strong vine. Hissers will fight only as a last resort. Hissers are very helpful and assist Hazard and his father.
