Hidden Islands are stages in Sonic Rush Adventure, scattered throughout the world map of the Sol Dimension.

Overview

These are short levels, some of them required to further progress in the game's story itself. Upon finishing any particular Hidden Island, the player may unlock missions (which can be played through Marine back at the house on Southern Island). Some of these missions reward the player with Sol Emeralds which allow the Last Story to be unlocked also.

The Hidden Islands work in the same way as the main islands in the way that every time the level is completed through stage select, or venturing to the island itself, the player is rewarded some Materials and Rings, which are both used to create and upgrade the watercraft used to travel the sea.

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 stages 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.

The following list also includes what types of Material can be earned for completing them, and whether they are optional or not.

Hidden Island 1 Hidden Island Blue and Iron Material No
Hidden Island 2 Hidden Island Blue and Iron Material No
Hidden Island 3 Hidden Island Blue and Iron Material No
