ALVINNN!!! and the Chipmunks 2015 Season 3 Episode 4 - Spoiler-Itis / Something Fishy >Theodore wins a goldfish at the fair, which he names Henry. The following morning, Alvin and Simon find Henry belly-up in his bowl, and try to bring him back to life before Theodore finds out. When Simon's electro-shock fails to regenerate the fish, Alvin goes back to the fair to try to win another goldfish, while the Chipettes distract him. Alvin fails to win a new goldfish, so Jeanette buys one at the pet store, which Alvin and Simon slips into Henry's bowl without Theodore knowing, but they feel guilty about switching the goldfish behind Theodore's back; eventually, they learn that Theodore knew the difference anyway, because the goldfish that he won at the fair was a plastic toy.
