History
While burrowing for oil underground, Snake Probes caused a mysterious green liquid to leak into the Great River. After Sonic the Hedgehog failed to catch a fish, he returned from the Great River with the green liquid on him. Seeing this liquid's ability to grow plants rapidly, the Knothole Freedom Fighters get out on the Great River in one of Rotor Walrus' boats to find the source of the green liquid. During the trip, however, the group got caught in a whirlpool that pulled them into an underground lake.
