37 Ninja Kids (1982)

The ninjas are awaken in the morning. One young boy is lifted nude out of his bed but his genitals are not seen. A boy of about 5 stands naked facing the camera but hold his hands over his genitals. In a hurry to dress for the morning review, one boy doesn't have time to get his trousers on. The camera scans down his body but his shirt tail protects his genitals from view.

The kid ninjas practice very athletic, gymnastic type maneuvers that are digitally enhanced feats. Boys watching this are very likely to try a perform these impossible stunts possibly resulting in injury.
