Egg Snake

Egg Snake is the sixth boss of Sonic Advance, located in Cosmic Angel Zone.

This boss is difficult as the player must flip Dr. Eggman upside down by jumping on the mechanical rope that he is sliding on. Then they must quickly attack the exposed doctor. If the player loses rings from hitting the spikes on the other side or hit by it's energy balls, the rings won't bounce. They will instead fall down and therefore be irretrievable.
