While on a hiking trip in Japan, Pooh, Sonic and co. settle in and have fun. Cheese is swimming when a current blows them 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 Doctor Eggman, Lord Zedd, Rita Repulsa, Goldar, and Rito Revolto, also hiking in the vicinity, show up with a new Eggbot, collectively thinking that the gang is there because they found a Chaos Emerald. Eggman attacks the Chao colony but is defeated, however the destroyed robot is leaking oil into the lake; Sonic and Arcee clear the lake by running/driving around it with full speed.
