Watched a Sinbad color movie on TV in the early-to-mid 1970’s. It may have been dubbed, but the scene that I really remember is of a man trying to follow our hero and gets off the track. He is very pissed and sees a frog near his feet, which he snatches up by one leg, swings the other leg into his mouth where he then bits the leg securely then violently yanks down on the leg in hand thereby splitting the frog nearly in half (from tail to head) and the frog bleats a quick, loud “WACK” sound (not quite like a duck). The entire action takes only 2 – 3 seconds and is startling and hilarious in its effect. What movie is this?
