Sonic Tonic

6.9Action & Adventure, Animation199921 min

A speed enhancing fluid deemed Sonic Tonic is created by Robotnik to make him as fast as Sonic so that he may finally catch him. Robinik's plan is successful and Sonic is captured, yet when Dingo begins to feel the side effects of the tonic, Sonic is able to make a run for it with a vial of the tonic in tow. Unaware of the side effects of the tonic, Manic and Sonia, envious of Sonic's speed, decide to use the tonic on themselves.
