Prowler

the Prowler would be like the sniffer, an ancient mob that would need to be resurrected from extinction. its eggs could be found rarely in jungle temple chests. This mob would be a mix between a bear and a saber tooth tiger; it would have the body of a bear, dagger like teeth of the saber tooth tiger as well as the tail of a saber tooth. The prowler would have purple and blue fur with purple on the top and blue on the bottom, the Prowler would have blood red eyes and razor claws.

The Prowler could introduce a new mechanic where if you don't feed it for three days it would turn hostile, therefor you would have to take good care of it. If you manage to keep it passive it will help for you and retrieve the items like an allay. In short it could be a cool pet however if you don't take care of it, it will go feral.
