Kea, Milford Sound
These little buggers eat cars. They wait at traffic lights until the traffic haults and then attack the rubber seals round the windows.
You're not allowed to eat them back. They're "endangered". Probably on account of they're diet - but then again, there's a bloke in Russia who eats bicycles and light bulbs and he's still alive. Maybe. He was on Record Breakers and to be honest I haven't heard any news of his status in a while so he could be dead. Lets say alive for arguments sake.
