 There are several different versions out there, depending on how much the  censors cut from the sacrifical scene, and from the scene where the guard  gets caught in the grindstone. However, after Indy escapes from the Black  Sleep and gets his hat back, he punches out one of the guards. The subsequent  shot is a kid smiling at him. Usually, this is a little boy, but in some  versions, its a little girl.
