I remember seeing a cartoon as a kid that takes place in a jungle. I remember the characters travelling up an elevator in a tree up to a big tree house with a glass domed roof or something like that?
The bad guy had black hair and a black moustache and a pink shirt with black trousers. The good characters were a blonde lady wearing a yellow jumpsuit and a guy with a brown jacket and brown trousers.
Both the bad guy and the good guy inhaled a vapour from a ring which made them beast-like (hairy and muscular) and they both fought while the tree house was falling.
