Shantae's life-long friend and ally, Sky is a war bird trainer whose profitable egg hunts often span the known reaches of Sequin Land. Sky can't wait for Shantae to see more of the world and life's surprises, and seems to be in a hurry to grow up. Sky is a sort of desert rat, always nesting in out of the way places at length. For this reason, Shantae and Sky tend to have more unexpected reunions than planned visits. Even apart, their friendship is a strong one, and Sky's opinions hold equal value to Uncle Mimic's in Shantae's mind. Sky keeps a war bird named Wrench, and she is rarely seen without him. Wrench is a dangerous weapon and is totally reliable, even following Shantae's orders. For some reason, Wrench regards Bolo as prey, and takes every opportunity to prove it.
