The Indian in the Cupboard 1982 publication.

The Indian in the Cupboard is the first of five gripping books about Omri and his Iroquois Indian, Little Bull. For Omri, it is a dream come true when the plastic American Indian he locks into an old bathroom cupboard comes to life. Little Bull is everything an Indian brave should be - proud, fearless and defiant. And the size of Omri's finger. But being in charge of a real, live, but tiny, human being is a heavy responsibility, as Omri soon discovers. And when his best friend, Patrick, is let in on the secret, life-changing decisions lie ahead.
