Overlooked is an episode of the ALVINNN!!! and The Chipmunks series.
Simon enters his hidden closet room in order to begin creating a video introducing the testing of his newest prototype, the invisible suit. In the living room, Alvin and Theodore practice for the talent show as Simon, in his suit, messes with Alvin. Simon terrifies them briefly and reveals his invention. Simon refuses to let Alvin borrow it for he never returned his pocket-sized utility toolkit. After confirming Simon's absence in the Seville House with Dave, Alvin enters Simon's closet room and takes the suit to mess with Dave in his study, help Theodore practice, and scary Derek for moving in front of Jeanette in line at the skate park. Back home, Alvin frantically tries to unzip the suit but it's stuck so he has Theodore try to help. Simon walks in and confirms Alvin took his suit by claiming he has a crush on Brittany, which he denies. Simon chases him around the room before Dave informs them of dinner. Alvin doesn't go downstairs until Dave calls him down, almost sitting on the chipmunk returning to his chair. Dave grounds him and tries to give him a lecture about respecting others' wishes only for Alvin to keep moving. As he sleeps, Alvin has a nightmare of living only with invisible people since his family can't see him. In the morning Simon drags and pushes Alvin to school as Simon envisions the Science Lab's Mega-magnet being a solution. He calibrates the magnet and not only unzips the suit, but also reacquires his toolkit from Alvin's pocket.
