Genie Egg

Genie eggs, also called spirit eggs , are objects that appear in Sonic and the Secret Rings.

Physical appearance
Genie eggs are multicolored eggs that are slightly bigger in size than dinosaur eggs. The colors of the egg are yellow, brown, red, and green, which are all intertwined into creating a unique pattern.

Overview
Genie eggs appear in a Special Challenge mission, where the player has to destroy 5 of them to complete said mission. They can easily be destroyed by using the Homing Attack on them three times, although other methods are possible as well, such as using Fire-type skills.
