The Egg Turtle is one of the eight boss mecha from Sonic Rush. Piloted by either Dr. Eggman or Eggman Nega, the Egg Turtle is fought underwater at the end of the Water Palace stage. It will attack Sonic or Blaze by charging or by belly-flopping. When the water drains from the arena, it will become immobile and try to attack by extending its neck and snapping with its mouth. Its head is the weak spot which can only be struck when the Turtle is beached after the water drains.
