A rogue Cognitohazard caught by the sorcerers at the IAMC, it now serves as the ward within its walls, subduing prey with hallucinogenic spores and swallowing them whole. 

The silver collar around its neck prevents it from escaping into the suconscious, tying it to its amphibious, corporeal, pleasantly squishy form. 

Better idea not to provoke it, though. Don’t want to end up as its lunch.
