An alien family was on a vacation on Billy's planet. They used magnet-cubes to teach their kid basic math. However, they had to leave in hurry as the wife forgot to turn off the cosmo-oven at home. So, Billy is now left with a bunch of magnet-cubes he needs to remove from his fields in order to plant the crops and feed his animals.
