"The hungry critter — dubbed Munchy — has been biting fist-sized chunks of metal out of Nora Ziegler's SUV. It's already ripped two 6-inch panels out of her Toyota Sequoia and seems intent on eating more."
They've got 4 other cars that Munchy shuns, so I wouldn't say he's got an "appetite for destruction." He's got an appetite for Sequoia. He's a veritable connoisseur. The discerning Munchy. In fact, "Munchy" seems disrespectful. I'd call him Li'l Nibbles.
