Fantasy Story Idea!!! Please answer quick?

Hmm . . . Teeny Tiny gets kicked out of Santa's workshop because he's too small. He goes into the North Pole town or whatever all depressed and somehow overhears the Grinch coming to rob Santa's workshop. So he tries to tell Santa and the elves but they don't believe him. He stops the Grinch himself (somehow using his size to his advantage) and is excepted. :)
