ALVINNN!!! and the Chipmunks 2015 Season 3 Episode 11 - Independence Day / Opposites Attract >Dave is fed up with Alvin and Simon constantly fighting, and disciplines them for it, but another fight between them ruins Simon's latest scientific experiment: a ray that can magnetize anything it hits. After becoming accidentally magnetized to each other, and desperate to keep anyone from finding out what happened, Alvin and Simon pretend to be bonding with one another - even going so far as to put up a front that Alvin is protecting Simon from a pair of men who are after him. Meanwhile, Simon makes repeated attempts to meet with a pair of scientists to help them out of their situation, only to be scared away by Miss Smith, who presumes them to be the men who are looking to hurt Simon. Eventually, Alvin finds the missing part to Simon's invention in his bed, and Simon is able to fix it and separate them.
