Sixth-grader Brad makes the mistake of drawing instead of paying attention in class. When Brad’s parents ground him from drawing, his bratty little brother Daley rubs it in.
Later that night, Brad is surprised when a mysterious crow delivers a pen to his bedroom window. Missing his beloved drawing and frustrated with his brother, Brad uses the pen to draw a Daley-Destroyer, a giant slimy green creature that he envisions “getting” Daley.
