Magnetic Pal

Nick's best friend Zack comes over for a sleepover, but Anne doesn't want anyone else to know about the androids, so doesn't invite them over to her magnetism experiment. When Pal is accidentally turned into a magnet, Zach gets drawn into the junkyard anyways thanks to his metal backpack. He ends up helping demagnetize Pal, and becomes the newest member of the junkyard crew.
