Nadalada Was A Nothing Head by Terry Lancaster

Hippy McTripperson travels the world looking for answers to life's big questions in this whimsical prequel to Here Come the Nothing Heads. Lost in the desert then lost at sea, Hippy eventually loses it all in a strange land down by the river. That's when the Nothing Heads begin to arrive in Happy Hollow, each seeking something completely different and each finding the one thing for which they never even thought to look.
