Doctor Dellbert Doppler

This sort of dog is very klumzy. He thinks Treasure Planet quite 'interesting'. Dr. Doppler is a sort of scientist and a bit absent-minded. This docter... I mean this ASTRONOMER helps Jim finding the treasure. When Jim's mum doesn't want that Jim goes, he fetches her over to let Jim go to Treasure Planet, he says he will come along on tha ship.
