This movie I believe played on Nickelodeon or Disney in the 90's.
I remember a little boy always being bored. After Dinner he goes to his room with this puzzle box and opens it and a little Purple Creature comes out and tells the boy that he is going to take him to a Magic World...
The Boy Said He Had Never Seen Magic Before...
The Purple Creature Says... "Youuuuuu'lll Seeeeee"
