Carve

A mutant watermelon who is out on a search for noses -- don't ask why he wants noses, he just does. To rip off. Of people's faces. And eat. And then search for more noses.

Just avoid him.

He sprints surprisingly fast, so if he approaches you and reaches for your nose, your best line of defense is to stab him anywhere on his rind. If you don't have a knife, patting him on the top of his head has a chance of calming him down, giving you an opportunity to befriend him, meaning that he won't try to rip off your nose anymore, and will simply sprint away as far as he can to find other people.
