Sebastian is a black fox that has a brother named Flicker.
Sebastian is a black wolf that is very hyper, and acts innocently nice. She has a brother named Flicky, and a cousin named Flacky. She is friends with almost everyone in Happy Tree Ville, and has never killed a single soul, but she tries to stop her brother and cousin from killing. Sebastian also loves lolipops, and always appears with a lollipop, and sometimes steals lolipops from Nutty. She even ripped the lollipop off his head, causing his skin to get ripped off in the episode Fight Fire with Fire. She doesn't appear in a lot of episodes, because her brother is always with her.
- She was named Sebastian due to her unforgotten cat named Sebastian that died a long time ago.
