The Spy Scope is a legendary telescope that floats on a platform high above the desert. It is sentient and capable of speech. In addition to being able to see large distances, it can also look into the heart, mind or soul of a person to see if their intentions are pure, and can teleport people great distances by casting a light.
In Shantae it helps Shantae locate and travel to Risky Boots' secret island hideout, allowing her to stop Risky's TinkerTank. The Spy Scope is found high in the sky in the Ladies Desert, to the right of Oasis Town.
