Bugs Bunny’s rabbit hole is flooded out by heavy rains at the opening of the 1952 cartoon Water, Water Every Hare.
Bugs is under water, but that doesn’t stop him from sleepwalking—to get a glass of water. He even uses a towel to “dry off” his mouth.
Imagination by writer Mike Maltese gets the cartoon off to a great start. Animation by Ben Washam, with drips and other effects by Harry Love.
