Dr. Robotnik is first seen putting the finishing touches on the Stopper Zapper, after which he demonstrates its power by firing a beam at Scratch, turning the chicken robot to stone. After Grounder messes with the petrified Scratch (by tickling his beak with a feather duster, squirting him with a fire hose, then smacking him with a large hammer until it rebounded and injured Grounder himself), Robotnik re-activated the beam, restoring Scratch to normal (after which he sneezes, gets a headache and complains about being wet, which Grounder simply shrugs off as a bad dream, and tries to hit Grounder.) Once the testing is finished, Robotnik orders the two Badniks to take it out and zap Sonic.
