Ned's Newt

Ned's friend Doogle has a pet dog, an obese, listless dog named Lummox. Doogle, when overhearing his parents talking about fleas on Lummox's fur, thinks his parents are going to get rid of him, and feeling sympathy for the fellow pet, Newton tries to prove Lummox's worth by setting up a series of situations where Lummox does incredibly useful things for Doogle's family.
