The game has two different kind of bonus stages. The first (hitting a large ring) sends you to a Blue Sphere stage where you get a Chaos Emerald for collecting all blue spheres, and the other stage (hitting a star lamp post after 50 rings) sends you to a bouncy gum-ball machine where you can collect different force fields, 1UPs, rings.

If Sonic is sucked up by Robotnik's propeller in the Hydrocity Zone while being Super Sonic, his sprite will change back to the regular Sonic sprite while still retaining his Super Sonic abilities and will also not lose any rings. He will remain this way until the level ends. This was fixed in "Sonic 3 & Knuckles". See more
If the game is finished with all the Chaos Emeralds, dolphins can be seen following the plane in which Sonic and Tails are riding. Complete the game without all the Chaos Emeralds, and there are just birds following the plane. See more
