Sonic Underground

Sonic Tonic (1x15)

Data di messa in onda: Feb 24, 1999

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?
