They are helped by an original Disney Imagineer Wayne, who tells them about a riddle called "The Stonecutter's Quill". They go to different attractions, and realize that the riddle refers to the first pen that Walt Disney ever owned. Once they find the pen, Finn realizes that he can defeat Maleficent with the pen.
