It can also speed through water and is a lifesaver if you have it in your possession and find yourself swimming but about to run out of oxygen with no air bubbles in sight. The drill is capable of burrowing through the sandy soil that you find in the game's earlier stages.

Yellow- Yellow wisps are capable of transforming into a powerful drill.

That fact will come in handy on occasion. However, note that he also is capable of smashing through destructible black crates that Sonic himself can't eliminate. Thus, he's typically only useful when you see telltale crystals positioned in out-of-the-way locations.

Cyan- The cyan (light blue) wisp can convert himself into laser energy that bounces along the various crystals placed throughout stages.His seven friends are the ones that you'll use to activate more special abilities, as outlined below. The White wisp simply fills your special meter with energy so that you can dash. Often, you can pick up another wisp of the same color to keep your power active, which is required in some cases if you want to do everything that is possible within a given stage. When you put a wisp to use, its power will last a certain amount of time before expiring. When you collect a wisp, you'll keep and hold it until you either use it, finish the stage or you collect a different type of wisp (you can only carry one color at a time).

That means that you may need to return to old stages frequently if you want to collect everything in the game. Once you unlock a new wisp type, you can revisit old stages to find that holographic capsules have been given form. You'll have to unlock each new wisp type, which happens automatically as you progress through the various planets featured in the game. The game gets its name from alien creatures called wisps that you can use to aid you as you work through the adventure.
