Plot
Traveling around on the island, Eggman plans to set off the hotspot with an explosion. While Sonic, Knuckles, and Rouge investigate the subterranean landscape of the island, the others are trying to locate Dr. Eggman. Unwittingly, the intruders awaken a giant Mogera-esque robot that attacks them. Over the course of a pitched battle, Decoe and Bocoe reject Dr. Eggman and try to help, but are sent flying. Sonic then throws Eggman's explosive into the robot, causing it to explode. The island begins to sink but everyone escapes. Decoe and Bocoe then emerge, having been rebuilt by Tails and Chuck and denounce Dr. Eggman.

Dubbing Changes

 * At the end of the Japanese version, Decoe and Bocoe were originally destroyed when the island volcano erupted, and Tails and Chuck repaired them. This was changed in the English version to have Decoe and Bocoe say that they escaped from the island in time.
