Puppetman (Found 1987 CBS Pilot)

One day I was watching cartoons while what caught my eye was a special episode of Sonic Boom airing at 10:00am next which was weird because in my country, new episodes would air at 8:30am.

The intro started as usual, but when the intro ended, a title card popped up saying "The Death of Team Sonic". The scene cut to a hospital where Sonic, Tails, Knuckles, Amy and Sticks are laying in beds. Sonic said weakly to Tails "Tails... ... why were we in hospital..." The gang suddenly died while the doctors said "Medic!". The scene cut to Sonic's shack where a naked Eggman is seen dancing to the Sonic 3 boss theme. The episode ended after five minutes of Eggman.
