Sonic Rush Adventure: Part 4: Ocean Tornado & the 1st Johnny Race (Red Chaos Emerald)

Description :

After building the Ocean Tornado, a large vessel for deep‑water travel, Sonic and Tails use it to reach a shallow area west of Machine Labyrinth island. Along the way they encounter Johnny, a fast waterbike racer, and Sonic challenges him to a race that serves as a special stage; winning earns a Chaos Emerald. The encounter does not heal the ship’s health, and the team plans a better route to the next island.
