Spheres bear a resemblance to frogs' eggs, which apparently have a more solid orb inside the weaker one.
Sonic the Hedgehog CD
In Sonic the Hedgehog CD, spheres can only be found in the second and third zone of every timeline in Collision Chaos. Dozens of these bumpers appear in large ravines where the player has to clear a way through them to proceed with the zone. As the player bounces off a sphere, one hundred points are granted. Spheres also appear during the boss fight against the Egg Tilter, where they float individually.
In the present, spheres consist of transparent red orbs with a red core. In the past, their orbs are transparent yellow and their cores are green angular-shaped rocks. In the good future, they have transparent cyan orbs with green and yellow, angular-shaped rocks for cores, while in the bad future, they have transparent orange orbs with dark blue and green cores.
Sonic the Hedgehog Triple Trouble
In Sonic the Hedgehog Triple Trouble, spheres appear in Meta Junglira Zone. Here, they float above wide areas, and their orbs are transparent green with purple cores. However, these spheres do not give points when the player bounces off them.
In Sonic Mania and its expansion Sonic Mania Plus, similar objects appear in Mirage Saloon Zone. They behave much like they did in Sonic the Hedgehog CD, except they only give ten points after each bounce. They come in two variants: magenta orbs with a yellow-orange shape inside of them that are used in inside areas, and cactus-colored piñatas that are used in outdoors areas. All spheres in this game only launch the player upwards.
