Happy Go Ducky (1958)

The Easter Bunny delivers an egg to Tom and Jerry, which soon hatches into an adorable little duckling. Trouble arises as the mischievous duckling finds its way into all sorts of water hazards: the aquarium, the water cooler, the bathtub, and the sink, prompting the boys to repeatedly come to its rescue. They attempt to return the duck to the Easter Bunny, but it doesn’t work out. Finally, they leave it in a park pond, hoping to be rid of it, only to discover that the duckling brings its friends back home with them.
