The trainees are preparing for a game of tandem chug-tag. Koko and Wilson need to complete their Advanced Storm Training so they don't have time to practice for the game. In a hurry to finish, Wilson turns the storm maker up so high Koko is floating in the wind above the tracks! She shouts STOP and lands on the track with a thump. One of her wheels is damaged! Morgan has run out of spares so Wilson takes the magnetic crane out to try and find enough metal to make a new wheel. He turns the magnetic crane up to it's highest setting and gets stuck to it. Wilson manages to wriggle free and heads back to the depot. Along the way all the metal objects near him start to stick to his body, he's covered!
