|Crystal Egg boss|
Concept artwork of the Crystal Egg Boss.
It takes place inside a lightning chamber, which Dr. Robotnik makes extra-fatal by throwing gyrating, flower-shaped energy bolts into the mix. However, the boss actually isn't that difficult if you stay inside the transport chutes until the chamber clears; at which point you can leap out, attack Robotnik and dive back in to safety before his attacks renew themselves.
