Well, sorry if this is in the wrong place. If so, move it to its correct location. I have some guesses to how and where some unused sprites were used that other sites don't say. 1. The bounce and crush Sonic ball. According to the concept art, the ball looks like as if it would have bumpers on it. Which shows it would most likley be used in the pinball zone, Casino Night. And another reason it would be in Casino Night, is how the ground looks in the concept art. Bouncing around an area to slow down Sonic. If Sonic were to jump into it, it would bounce him back. like a bumper, so it would bounce around ans a mobile bumper. If Sonic were to let it crush him. You know what. But this therory can be tottaly bummed out due to the sprite found in the rom. But that might be because the sprite was incomplete. Any questions? 2. The 3 missing Sonic animations. The laying down pose: It might have been used after you land on Tails plane in the ending, seeing that Sonic might have been tired after a long battle against The Death Egg. (Yes, that's the name of the final boss machine, I think) The looking at screen pose: Sonic might have looked at the screen before giving the victory pose for the game being finished like in Sonic and Knuckles. Pulling sprites: Sonic might have possibly pulled a swich to open a door, like in Sonic Heroes. Questions? 3. The futuristic lampost. Well, at one point Sonic 2 was to have time travel in it, right? Maybe at one point, depending on which level you were in, like in Metropolis, the lampost sprite would be that one, cause its futuristic. So theres a possibility that the ones in the normal game would be the present. But there could have been a past one too, for like Wood zone, I think it could have been a possibility. Questions? 4. Ball item in Oil Ocean. Theres a chance that the ball was once meant to break walls open to go further into the level. So basically you would press the swich and the ball would go to the wall and break it open. Similar to the blocks to break the wall open in Ice Cap Zone in Sonic 3. Questions? I might have more later. I think I have supporting facts for all of them.
