Potato and his friends arrive at Driving School and initially had fun at the playground, even eating carrots that are not supposed to be consumed. They are then met by Driving School staff consisting of Molcars Thumb, Shoe, and Knee, a military-style drill instructor, and his secretary. The drill instructor seethes at the new arrivals' shenanigans and backs them to another part of Driving School. There, he shows how proper Molcars should look like, standing erect with no decorations and in "proper form." To enforce this, Choco is deprived of her hair flowers (making Rose fear for her earrings) and the student Molcars are repainted mostly white with standard decals, student caps, and student license plates that read "RETAKE MOLCAR," all to the surprise of their arriving drivers. The drill instructor then gets inside Potato to check on the latter's interior, but Potato unconsciously tosses him around and ejects him through the back end. The drill instructor is then given a cold stare by all Molcars, even Thumb, Shoe, and Knee. Seeing his plan for assimilation backfiring, the drill instructor undoes his changes to the student Molcars and even has Choco's hair flowers returned to her.
