Crockashark
A cross between a crocadile and shark, found in shallow muddy waters around the southwestern tip of austrailia and sometimes in the canal that goes past our office. They have a tendancy to bite those who anger them with non funny remarks / bad accents. A mysterious creature, the crockashark is know to have a penchant for tank tops.
