I've edited my characters inventory to be a little more extensive, but he's still on the poor side. As far as Peter's personality, 'doing stupid stuff with no regard for anyone else' isn't really the vibe I meant to set out - he cares a lot about other people, he's just not the brightest and prone to impulsive decisions (my hope is that since this is a cartoony setting, we're in a world where being impulsive is a trait of a likeable rascal, not something likely to get everyone killed :P ). 

Of course, the choice is up to you, so I can fix it if you really don't see it working. As it stands, I don't see these characters as being unable to get along; there might be some friction, but nothing that would make cooperation or adventure impossible.
