Trashini is a Grouch who appears in a season 45 episode of Sesame Street. She was the smelliest girl at Oscar's high school, as he recalls. In a flashback, we see her accompanying a nerdy Oscar to the school's "Enchantment Under the Sewers" dance and he's pleased when she tells him she's having a rotten time. Oscar attempts to treat her to some mud pie, "on him." The waiter takes it literally and slops the slice onto Oscar's tuxedo, leaving the first of many memorable stains (shaped like a triangle).
