Marsupilami S03E04 - Marsu the Menace

Felicia's big city plans are threatened when she got notice from a soon-to-visit Aunchorman that people are looking for more "Environmentally Friendly" homes these days. Hiding the pipelines and other evidence that her HQ is fueled with toxic waste, her company unwittingly expose Mars to radioactive sludge while he's out getting food for his family, and comes back with his fur glowing in the dark and a scent that destroys several plants and animals in his path! Hector and Aunt Diane are at wits end, but manage to cure Mars and expose Felicia as the phony she is.
