Grampa in Oz — John R. Neill

When King Fumbo of Ragbad loses his head in a storm, Prince Tatters, accompanied by the wise and wonderful old soldier Grampa, sets off to find the king's head, a fortune, and a princess. With Bill, a live iron weathercock, they visit a Wizard's Garden and discover Urtha, a lovely girl made all of flowers—and proceed to fall, swim, explode, sail, and fly above and below Oz and Ev. Grampa and company eventually meet Dorothy herself, traveling with a Forgetful Poet in search of the missing princess of Perhaps City who has been condemned to marry a monster!
