The Indian in the Cupboard

I recently finished a book called The Indian in the Cupboard. It is about a boy named Omri who gets a toy Indian for his birthday which he doesn't want. His brother, Gillon, gave him a cabinet he found in the alley and his mother had the key to fit the lock. During the night he wakes up to a sound coming from the Indian whom he had locked up before he went to sleep. But how could the Indian make any noise? Was it alive? Then, his friend, Patrick, makes a cowboy named Boone into a human. Trouble ensues because the Indian and the cowboy are constantly at odds.
