A shrinking ray is a device that has the power to transform a target into a much smaller version of itself. A fixed version of this machine could once be found on the Miracle Planet, which Sonic the Hedgehog used to shrink himself and travel through time to save the planet. Nack the Weasel also possessed a portable version of this contraption, using it to shrink all the sand and treasure in the Lost Pyramid of Sandopolis. Once he lost that, he began making smaller versions in the guise of capsules as well as a transformation belt.
