Looks like Im keeping this guy :)

This is a carnivorous, amphibious creature that is adept on land and in water. The structures on the tail, back, and neck are gills. The structures on the head are Rhinophores, smell/taste organs.

And the frills above the eye are sensors to detect electrical fields.
Stands at about 5 and a half feet at the top of the head. Its nostrils close when underwater. It has webbing between its elbow and knee.
