Mr. Bean S03E13 - Hopping Mad!

Mr. Bean takes frogspawn from the park to his flat, but 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 a bus, but when he sighs in relief, Scrapper (who manages to survive the attack) gives him a frog who drags Bean with its tongue.
