Mr. Matthews cares deeply for his animals, but unfortunately the feeling doesn't seem to be mutual - one of his charges mangles his ear when he neglected it too much. He is particularly proud of his prize boa constrictor, Joanne.

He seems very attached to all the animals in the store, having named them all including the goldfish. When he suspects (correctly) that Quinn has accidentally let Travis the canary escape, he freaks out, but is placated when Quinn lies and tells him Travis was sold.

Unfortunately, his pet store is reduced to chaos when Quinn accidentally frees Joanne, a number of gerbils are let out, and iguanas attack Jeffy.
