The prototype Star Post seen in earlier versions of the game still exists. When deactivated, it is yellow, rapidly flashing white and red once Sonic has passed by. | |
The seesaw from Hill Top Zone (Scrap Brain Zone) can be placed in Emerald Hill Zone (Star Light Zone), complete with different colour scheme. | |
