Killer Tongue(1996)

Melinda Clarke stars as the latex-clad Candy, a beautiful bank robber hiding out at a desert gas station run by nuns while awaiting her boyfriend's release from prison. After being exposed to a falling piece of alien meteorite, Candy grows an extremely long homicidal tongue with a taste for human flesh, while her pet poodles--who have also been exposed--transform into flamboyant drag queens.
