I seen this movie when I was younger about a boy who recently moved and found an imaginary friend that in the end turns out to be this mummified looking boy king or pharaoh that wants to keep the kid in this catacomb-like tomb with him forever as a playmate. I thought the movie was called Playmate, but, I can not find it anywhere. I have searched by plot, genre, title, etc. PLEASE HELP!

Imaginary Playmate (TV 2006) - IMDb (http://www.imdb.com/title/tt0928390/)

It is with a girl and not a boy...
