3x47 - Mr. Bean: The Animated Series

Mr. Bean takes frogspawn from the park to his flat. However, once the frogs become adults they turn aggressive. While dealing with the frogs, Mrs. Wicket and her two friends are having a party in which the floor collapses and the frogs attack Mrs. Wicket, Scrapper and her two friends. Bean then finally lures the frogs by throwing meat into the bus but when he sighs in relief, Scrapper (who manages to survive the attack) carries a frog who drags Bean with its tongue.
