The Magical Pen

Disney Fan-Fic. Maybe one day I'll make a non-Disney version of this. Comment in the story.
This story is going to be told by a narrator.

Young Walt Disney and his brother Roy set off to another day in the Disney Brothers Studio, and Walt starts drafting some character ideas for his laugh-o-grams. Devastated after his cartoon star Oswald got stolen from another company, he decided to get back on track and make another cartoon that will be a hit. After getting a special expensive pen for his birthday, he decides to use it and draw some cartoons. But what he doesn't know is that his pen might have some magic. What will happen when he uses this Magical Pen?
