This beautiful art piece, made by Reva_the_scarf (FA: http://www.furaffinity.net/user/revathescarf/), tells the story behind the bitemark in Bing's left ear. At a very young age Bing got in a fight with his older brothers over this toy with a flashing light in it. They were very annoyed, all those times Bing "borrowed" their toys with lights in them, and this time was one time to many and they tore a piece out of his left ear to teach him a lesson. Until this day it's still unknown if it worked :P
