Character description from manual[]
Leech is more then an inventor, he's one of the great scientific minds of his age. However, his jovial, capricious nature makes most people think he's just a goofy, nerdy tinkerer. Harry is more than willing to help Leech out of trouble, even though he has no idea what Leech is saying half the time.
