Special Stages Appearance

Sonic The Hedgehog The 1st Special stage was in that game the 1st ever sonic game the better appearance was in Sonic The Hedgehog 2 and they kept on going to make special stages but in sonic and Knuckles it was a bonus stage to get rings so the sonic series kept going up and kept on trying to beat super Mario with Nintendo's super system but Nintendo was trying to beat Segas 18-bit Sega Genesis so that's how they made cool special stages/bonus stages!
