A little fib turns into a big problem for Junior Asparagus! With dad's favorite bowling plate in pieces, Junior is sure to be punished until a strange visitor advises him to cover his tracks with a little white lie. Dad buys the story, but Junior notices his new friend seems a little bigger now and a lot less cute!
