Fantasy movie with a kangaroo who boxes his shadow
This is a fantasy movie at lest thirteen years old. There is a kangaroo in it who always boxes with his shadow and it boxes back, I think his name might be boxer. There is a teenage boy in it who is transported form our world to the fantasy world (like Never Ending Story) the boy some how gets a crystal that is rather small and has another dimension in it or something. He has to find somebody who knows how to open the door to the crystal up so he can retrive a powerful sword from it so he can fight the main villain.
