Chaos Emeralds (IDEA)

Chaos Emeralds would spawn every 5 minutes and would evolve the stand "Sonic" over time. If 7 of these emeralds are collected, the stand would turn into "Super Sonic." The chaos emeralds would come in various colors. To make it even harder to obtain "Super Sonic," you would need ALL of the different colored Emeralds, meaning that if you had already obtained the Cyan Emerald and found another, you cant use that other Cyan Emerald.
