Hehe, Maggot is a funny name. But some people might think you are a Slipknot fan! Might be better for a rat actually, as would Wormtongue.
There's also Huan the Hound. Or Bill, if he's one of those dogs that's so big he's pony sized and it looks like you could ride on him (do not attempt this at home, kids).
I have to say my favourite out of all these is Pippin, which is really cute, but not "eyuw" cute, if you know what I mean!
