Pirates in Oz

In which the old Gnome King attempts to capture the Emerald City and regain his magic belt, much to the horror of Peter, the Philadelphia boy who returns on a flying poetical pig to try to save Oz.
Hindered by a band of mutineering pirates, Peter is helped by a magic ship that sails through both water and sky, a king who wants only to be a seafaring cook, and Samuel Salt, the swashbuckling Pirate Captain himself.
