Nickelodeon is under fire for airing a topless cartoon female in one of their popular cartoons, 'Oggy and the Cockroaches'.

TMZ is reporting that Nickelodeon has since yanked the cartoon from the air and online. The March 5th episode of 'Oggy and the Cockroaches' featured full-on big, exposed boobs in one of the scenes.

One parent whose child spotted the XXX pic on TV tells us he was extremely unhappy and was forced to have a female anatomy talk with his 8-year-old son. It wasn't fun.

TMZ says that Nickelodeon was called for comment, but so far, no word back.

This isn't the first cartoon to feature hidden sexual themes. Here are some of from some classic Disney cartoons.
