Pirates' Island

 Pirates' Island' is the seventh Zone of Sonic Rush Adventure''. This location is actually ruins left behind by an ancient people, but the pirates, under the command of Captain Whisker, set up their hideout here, filling the valuable ruins with weaponry of all kinds, while remodeling the archaeological relics. '''

Being the final "regular" level of the game, Pirates' Island features a large number of game gimmicks: Trebuchets allows Sonic and Blaze to launch themselves into air while the thrown rock breaks down obstacles, high-preassure water cannons creates rails for Sonic and Blaze to grind on, large anchors which either acts as a platform or a large weight that can crush the player, fountains that can shoot people into the air, dolphins that can be ridden underwater, and finally timed gates that will close after a certain amount of time, thus blocking shortcuts.

The boss of this stage is Captain Whisker and Johnny. This is a somewhat unique boss fight in the Sonic series as the player faces two opponents at the same time. Whisker can breath fire, launch is fists at the player and can create shockwaves when stomping into the ground and Johnny can fire himself as projectile. The two of them can also attack together, by having Whisker throw Johnny at high speed, thus making Johnny a faster pojectile that can bounce off wall and becomes far more unpredictable.
