Toxic river



Yellow Water is an obstacle that appears in Shadow the Hedgehog.

Overview
Seemingly, after the destruction caused in Sonic Adventure 2, Prison Island's waters became highly contaminated and pousinous, making them deadly to living creatures.

Yellow Water rivers make up a big part of the Prison Island stage in Shadow the Hedgehog, as the player will more often than not find themselves traversing over the yellow water with the aid of an Air Saucer. Without the aid of an Air Saucer, or the invincibility granted by the Hero and Dark Shadow transformations, the player will be uunable to cross Yellow Water without constantly being damaged.
