Hidden Island

Hidden Island Overview

In Sonic Rush Adventure, Hidden Islands are scattered throughout the world map. These are (for the most part) short and optional levels, that are a reward for exploring the vast ocean.

Hidden Island Themes

Every Hidden Island has a "theme", which includes the background music, scenery, badniks, and gimmicks. Many Hidden Islands take their theme from one of the first five zones in the game. Others use the exclusive "Hidden Island" theme, which appears as grassy cliffs with islands in the background. The music playing during this theme is a remix of A New Venture. Badniks include orange barrel throwing robots and larger, purple ball and chain wielding robots.
