ALVINNN!!! and the Chipmunks 2015 Season 4 Episode 5 Simon Says / Sing Like a Canary Episode Title: Simon Says / Sing Like a Canary Episode Description: Simon Says:Alvin gets fed up with Simon always putting a stop to his crazy schemes, accusing him of being an uptight killjoy; Simon argues that he has a responsibility to watch out for his brothers and make sure they don't hurt themselves. Wishing he could figure out a way to get Alvin to see that he's only looking out for their best interest, Simon is talked into conducting a social experiment, by going along with Alvin's various different schemes and stunts, figuring that he'll eventually see how much dangering he's putting himself and his brothers into. Unfortunately, Simon's experiment results in having just the opposite effect, as Alvin believes Simon has loosened up and is actually fun now. After being coerced into haphazardly designing and building a scale roller coaster, Simon finally confesses his true intentions to Alvin, but is too late to stop him from trying out their new roller coaster, which sends him flying into the air. Even after being severely injured, and in a body cast, Alvin still feels the need to continue engaging in dangerous, thrill-seeking stunts, much to Simon's defeat. Sing Like a Canary:Fed up with Alvin's endless, selfish, and entitled demands, The Chipmunks' publicist severs ties with them, prompting Alvin to pout and shun everyone until his demands are met - even if it means missing out on rehearsals and concerts. During one such rehearsal, Simon, Theodore, and Dave discover a bird named Lali, who can sing just as well as they can, and pretty soon, have her feel in for Alvin's absence. Lali ends up becoming an overnight sensation, and people all over the country become infatuated with her, much to Alvin's angered dismay. As it turns out, Lali is actually somebody's missing pet bird, who just happens to be a Chipmunks fan, hence why she's able to sing their songs like they do, and her owners come to retrieve and take her home; Alvin sees this as his opportunity to reclaim his spotlight as the leader of the band, but only after Brittany finally convinces Alvin to drop his petty demands (without much success).
