Nickelodeon, one of the most popular TV networks for children and adolescents, has crossed the line.

Nick was always considered a safe zone in terms of content geared toward a younger audience, but an image of a naked woman's cartoon breasts in a recent episode of "Oggy and the Cockroaches" has some angry parents thinking otherwise.

In addition to worrying about violence and foul language in shows, parents must scan the screen for nudity.

The image pops up and disappears quickly in the episode titled "(Un)happy Camper," but not fast enough to go unnoticed. One parent, whose son discovered the inappropriate picture, was particularly upset and was forced to have a "female anatomy" talk with his 8-year-old son, according to TMZ.

An as-of-yet unnamed person is responsible for slipping the naked character into the March 5 episode, and there was definitely no glitch in the system as someone had to draw the large-breasted duck woman and place her into the background.

The network has pulled the episode off of its website and schedule, E! Online reported.

"Oggy and the Cockroaches" is an adaptation of a French cartoon "Oggy et les Cafards" from the '90s and has been on the air since February.
