A cartoon which first made its debue in 1999. In an alternate Mobius, there were few characters which were both in "Sonic Underground" and its predicessor, Sonic the Hedgehog (AKA: "SatAM"). The basic plot was Sonic, Manic, and Sonia were the heirs to the thorne, but were seperated when they were babies so that they could escape Robotnik's clutches and eventually fulfill a proficy using their Royal Medallions which could give them musical instraments of any sort, but of one type. Each episode had at least one group song, and, in many peoples' opinions, it was the worst Sonic cartoon ever made.
There are good cartoons, bad cartoons, and cartoons like Sonic Underground.
