Lenny zooms past Fanboy and Chum Chum on his treasured bike, Bikey. When he got to the Frosty Mart, his happy expression turned into a negitive emotion as he goes to work for another eight hours. After that, He heads back outside to see Bikey torn apart and broken. Later, Fanboy and Chum Chum wake him up. He thinks it was a dream, but Chum Chum pointed out it really happened! He gathered up all the possible suspects, and it was time to find out who broke the bike. Fanboy sees a bit of strawberry gum on Bikey's handlebars, only to find out it was from Oz, who Fanboy suspects it is. Oz then confesses that he broke the bike by stopping a pack of ninjas destroying it, but rode it for a while afterward. Soon, Dollarnator confesses he broke it by blasting it--only to make it come back again--and leaving for tap class. Janitor Poopatine then says he broke the bike by taking it away, followed by his cart bashing it up. Chum Chum then brings in three preschooler known as the "Burgle Brats", and thinks they did it. They confess they took it along with Boog's hat, and gave it back to scare him off, and get caught by the cops. But Lenny sees that they had a security camera along, and recorded the whole thing. Everyone watches the camera to see what happened, and it turned out to be Fanboy and Chum Chum! They confess they broke it because of a failed stunt jump. As a result, Fanboy and Chum Chum recieve the worst punishment Lenny ever gave them--force them to be parts of his bike while on his way home.
