ALVINNN!!! and the Chipmunks 2015 Season 3 Episode 21 Pizza Dash / Glory Days Episode Title: Pizza Dash / Glory Days Episode Description: Pizza Dash:The local pizza parlor is reduced to a one-man operation, as the owner is now overworked with having to do everything by himself: take orders, make pizzas, and make deliveries. Feeling sorry for him, Simon develops a team of artificially intelligent drones to help with the tasks. Unfortunately, with having artificial intelligence, the drones have the ability to learn and retain information, and pretty soon the whole town is under attack by an army of drones bombing everyone and everything with pizzas, prompting Simon and his brothers to battle the drones in order to defeat them and save everyone. Glory Days:While cleaning out the basement, Alvin and Simon come across an old box full of records made by "Seville and the Screaming Caterpillars", and find old photos that show Dave was once in his own rock band. Alvin worries that by he and his brothers entering Dave's life, they forced him to leave his previously life of being a cool rock star behind, and "turn lame". After learning that the Screaming Caterpillars are still a band, and reduced to performing in retirement homes, Alvin and Simon seek out to learn more about them; it is clear that one member of the band is still holding a grudge against Dave for bailing out on them, but the other band members explain to the boys that Dave simply grew tired of all the traveling and touring that came with being in a rock band, and wanted to pursue his own life.
