A dogfight with the Egg Fort over a savanna ends badly for both sides. Sonic’s Ring-powered spin slices through Eggman’s ship, but debris shears a wing off the X-Tornado, and Tails and Chris spiral down into the bush while the Egg Fort crashes into a swamp. Sonic, separated from them, passes the time racing a cheetah.

Grounded, Tails and Chris – who is suddenly more interested in animals than machines – discover a building firm putting up a dam that endangers the local animals. They take the case to a nearby city and rally enough protesters to halt the work.

Eggman has his own plans, and his ape robot E-65 Gorru-Gaooh ambushes Sonic out on the plains. In the brawl, robot and doctor flatten the construction site and expose the managers’ crooked scheme. Tails throws Sonic a Ring, the ape is destroyed, and the police arrest the two bosses – so in a way, the heroes decide, Eggman helped save the animals.

Key Moments
