SPEEPSHighway | Sonic Adventure: Unused Snake Path in Lost World @SPEEPSHighway | Uploaded 1 year ago | Updated 3 hours ago
There's this unreferenced path (s_ev) for the snake in Sonic Adventure' Lost World.

Even if implement it uses a different snake object (ObjectRuinSnakeEv) that was removed so it won't show up. I gave it the regular one to make it visible, they were probably similar either way.

The name could imply it was for some kind of cutscene but that's all there is in the game about it.
