A dog is guarding a vegetable garden and falling asleep. The dog then spots two gophers eating carrots. The dog disguises himself as a tomato vine and poses as an actual plant in the garden. The Gophers spot the tomato vine, grab a bunch of vegetables, and throw a pumpkin on the dog before striking him with a shovel. The gags are plenty as the Gophers continue to outwit their canine nemesis. Eventually, they launch the dog, via rocket, into outer space towards the moon. The Gophers, now triumphant, gloat that they will have all the carrots to themselves. But suddenly they hear a familiar "Eh..." and there stands Bugs Bunny who disagrees with their statement and laughs.
