Little Chao Lost

While on a hiking trip in Japan, Sonic and co. settle in and have fun. Cheese is swimming when a current blows him off course and into a stream. They find him again, and the river led him into a pool in a Chao colony. They take care of the Chao and play with them. However, the place is put in danger when Eggman, also hiking in the vicinity, shows up with a new robot, thinking that the gang is there because they found a Chaos Emerald. Eggman attacks the Chao but is defeated, however the destroyed robot is leaking oil into the lake; Sonic clears the lake by running around it with full speed.
