Female Muscle in Cartoons

Muscle Growth Nut

I just remembered something, from the old Nickelodeon animated-variety show, Kablam! One episode had the host characters' segments being repeatedly retooled by a new producer, and at one point they show up as massive superheroes. To quote June, the female host: "Cool! I'm cut like a rock!"

Admittedly, the Henry & June segments didn't exactly boast high-class animation, but it was memorable nevertheless.
