I love the Greylings. They run at you screaming to stop chopping down their trees and then slap you silly, hoping you'll realise what you're doing. Even better, after you've gotten a bit stronger and they realise you can (an probably will) hurt them, they stop, thinking "hmm, maybe I shouldn't slap that dude and make him angry" and they turn around, running away with their arms in the air. Funny. Annoying at times, but not dull!
