Thistle and the Shell of Laughter (The Fairy Chronicles #3) (Fairy Chronicles Series)

The Shell of Laughter, which is the source of all laughter on earth, has been stolen. It is the job of Staid, the elf, to distribute laughter all over the world using trade winds, siroccos, Zephyrs, jet streams, the Chinook, and other winds. Along with a leprechaun, a hedgehog, a witch, and several fairy friends, Thistle must help Staid recover the Shell of Laughter from Killjoy Crosspatch—the evil Spirit of Sorrow. During this adventure, the fairies meet a wood gnome, unicorns, and a bobolink bird. They also learn what laughter is made of.
