Spot helps around his grandparents place and helps out Grandma and hears some of Grandpa's story of his bygone days as a fireman. We also learn that Grandma is a good baker and her cakes has always won the contest at the carnival, and she's submitting another cake this year. Then Spot's friends drop by, and they save Grandma's cat from a tree, save the carnival from having no musicians after the musicina's float truck broke down, and join a parade with Grandpa's fire truck, and Spot gets to ring the bell. Grandma's cake wins the contest.
