His name is Moby. I got him from Warren from Treacher's Creatures. He is a voracious eater, and will devour fuzzies, pinkies, fingers and sometimes even rat pinkies!
They're surprisingly very fast animals, and they have very soft skin. So far I have had zero problems with him. When he's in a good mood, he is very friendly and loves people.
He has also become the subject of one of my doofy watercolor paintings.
