So, I was randomly playing through Sky Rail in SA2.

Then, I found this platform near where the Ancient Light is (so you use the spring then it is to the left of the two grind rails) where some weird things happen.

I managed to get Shadow to start moonwalking, walk in slow motion, start running backwards off rocks, walk backwards in slow motion, start hovering and stay in the same position and start slowly moving around without walking. Then when I bumped into the rock which the platform is next to, the screen went all fuzzy and pixelated and all these stripes appeared on the screen.

I used Shadow's weird floating thing, and I managed to somehow clip through the wall! Inside the rock is nothing but a hole through.

I activated the glitch on 2 player battle mode with every character, and it works for all of them, except only Shadow can clip through the wall for some reason. And Metal Sonic can't float (probably because he's too fast), instead he does this really weird walk that's a bit creepy.

Shadow is still the funniest character to activate this glitch with though XD.

Has anyone else come across this glitch before?
