Sonic 3 Adventures (Mandela Effect or Lost Media?)

I've been a big Sonic fan for my whole life, so I know that this show isn't a thing and never was. You're probably getting the title of AoStH confused with The Adventures Of Super Mario Bros 3.

The only DiC Sonic cartoon series after the first two was Sonic Underground.

Underground had Knuckles in it for a few episodes, maybe that's what you're remembering?

Nevermind, it was titled Sonic 3 Adventures.

Unnamed Episode- Sonic goes to Angel Island on the Tornado, trying to defeat Robotnik, when Knuckles leads them to a Special Stage Ring. Sonic must collect all of the Blue Spheres before the portal to their world is closed forever. (Note: Sonic jumps into the portal after collecting all of the Blue Spheres, with a Sonic 3D Blast-esq model jumps as the camera pans around him. I just wanted to mention that, as it looked great for 1995-96-or 97.

In all seriousness this cartoon could definitely lists and I believe you. Cartoons in the 90s could easily get lost. Maybe it aired but, very briefly and nobody recorded it.

Don't bother with this guy, it was one of many lame hoaxes he tried to perpetrate. He has since been banned for that. For example, here's his "proof" that he had a film reel containing an old racist cartoon:

If this did exist and you have a frame of animation, why don't you post it, if this isn't bull?
