1x15 Sonic Tonic
First Aired: Sep. 17, 1999 on Syndicated
Summary: Using the essence of a rare plant, Robotnik manages to make Sleet and Dingo fast-- maybe even faster than Sonic. The Sonic Underground manage to get hold of it, but can Sonia and Manic resist the temptation of taking the drug themselves and being as fast as Sonic?
