The Pet Store Sprite

In "The Pet Store Sprite" by Tracey West, Violet and her cousin Leon join the Pixie Tricker Sprite to stop a mischievous water sprite named Aquamarina who has been causing chaos throughout their town by making all the sinks leak and turning anyone who sees her into fish. The water sprite has made her home in a fish tank at the local pet store, where she is most powerful. The three fairy-hunters must find a way to lure Aquamarina onto dry land, where she can be defeated.
