Stripperella - Season 1 Episode 13 -

An asthmatic motorist runs off the road to avoid hitting an animal and slams into a tree. He is bitten by the animal -- a glowing werebeaver -- and he turns into a giant glowing werebeaver that runs amok chewing through anything made of wood and terrorizing the population. Stripperella must put a stop this rampaging werebeaver.
