He is a... bird beast, about the size of a medium-sized house cat.
His name his Razzel, Razz for short.
He cannot talk, he makes click and churr noises and bird sounds (he can mimic any bird noise).
Mazz understands him. He's a Carnivore and wil pretty much eat anything smaller than him or anything bigger that's dying. (However he's highly protective of the herbivore Dazzel).

His counterpart and Mazz's other pet is Dazzel: https://www.weasyl.com/character/23278/dazzel
The 2 are Mazz's pets or they're seen as wild animals in the Triassic era.
