It’s the annual Bicycle Race at Capital Castle and it is a tradition for all the ABC Monsters to take part. But as soon as the race is about to begin, Cherry Berry notices that one of the ABC Monsters is missing. Before long they realise that B-Monster is gone. He had even left his bike behind and Alice wonders why would he do such a thing. So Alice, Brian and Cherry Berry start their search to find B-Monster and the first clue leads them to Benny Bunny's house. He has left his bucket somewhere around his house, and now it seems that he couldn't find it. The three friend helps Benny find his missing bucket and along with it they find a clue. A clue that leads them to Bobby Bat, who needs Alice, Brian and Cherry Berry's help to find his missing banana to feed on. As a reward, Bobby Bat gave the gang another clue. This clue leads them to a bicycle shop where they find B-Monster inside getting a new bicycle bell. He can’t race with a broken bell, so he rushed off to the shop before the race begins. Now that B Monster has his new bicycle bell, everyone heads back to Capital Castle for the Capital Town Bike Race to begin.
