The whole back story behind Gloomy is hilarious
Gloomy, an abandoned little bear, is rescued by Pity (the little boy). At first, he is cute and cuddly, but becomes more wild as he grows up. Since bears do not become attached to people like dogs by nature, Gloomy attacks Pitty even though he is the owner. So Gloomy has blood on him from biting and/or scratching Pity.
You can get a bloodier version of Gloomy too.
You get Gloomy at Magic Pony in Toronto.
