Pierce's Hundred Dollars (1988) - Beverly Hills Teens Cartoon Episode Guide

In order to get the voice-activated Ultimo car, Pierce needs to save one hundred dollars from his allowance throughout the week. When Pierce spends all BUT $100 on stuff for a party to celebrate getting the car, he acts more deplorably than ever in attempts to save the money. Chester, Blaze, Gig and Tara try to get Pierce to spend the money so he stops behaving that way, and they just about succeed when they get Bianca to ask him out to a concert. But then they double-cross him by convincing him that Bianca'd go out with him with the Ultimo anyway...and then Bianca cops the two tickets Pierce had bought and returned, leaving Pierce alone as the others make for the concert.
