Rickety Stitch and the gelatinous Goo

"Rickety Stitch is a walking, talking, singing skeleton, the only animated skeleton in the dungeon who seems to have retained his soul. He has no idea who he used to be when he was covered in a living, breathing sack of meat and skin. His only clue to his former identity is a song he hears snippets of in his dreams, an epic bard's tale that could also explain the old fog covering the comical fantasy land of Eem . . . Oh, and his sidekick and only friend is a cube of sentient goo. In this race-to-the-finish final volume, Rickety faces all manner of new creatures on his ultimate quest to uncover the secret of Epoli and learn his true origins"--Provided by publisher.
