Adventures of Sonic the Hedgehog 143 | The Coachnik | HD | Full Episode

Robotnik invents a robot coach -- the "Coachnik", to put S and G through a "Training Camp" to improve their skills. Then Coachnik puts a bomb in Grounder's head as a booby trap for Sonic, and a football game ensues with Grounder's head as the ball.
Sonic the Hedgehog, the most fearless hero on Planet Mobius, uses his supersonic speed and teenage irreverence to thwart the comedically despicable Dr. Robotnik. Sonic’s idolizing little buddy, Tails, tags along on every fast-action, gag-driven adventure.
