Each day, Mr. Tickle blasts off to work in his cannon, but today something is wrong. Instead of giving a big blast, the cannon just sputters. It'll need to be fixed, but until then, Mr. Tickle will need to take the train to work. JoJo comes with him, but he misses the train. He ends up walking to work, but finds himself getting tired out. Fortunately, Mr. Muscles has been teaching JoJo and her clown class some new exercises, which he happily agrees to show to Mr. Tickle.
