"In this fourth hijinks-filled adventure, Squash and Ginny are preparing for another mission when Magnus suddenly arrives in search of the Staff of Knowledge. Much to everyone's surprise, it's not in the Spirit World--it's in the Human World. With Fern and Lotus's help, Squash and Ginny locate the staff right away. But before they can return it to Magnus, Squash tries to conjure snacks (obviously), accidentally triggering a massive power surge that causes the orbs to disperse throughout the Human World. The orbs are now lost, and the squad must retrieve them before mysterious forces get to them first"--Provided by publisher.
