A block of wood

We went to see a movie called"Mister Migoriums Wonder Emporium" In one of the scenes Dustin Hoffman gave Natalie Portman a supposed magic block of wood. He tried to explain to her that the block of wood was a metaphor for having possibilities. Later in the movie another character said "You are a block of wood." Little Maddy said in a loud inquisitive voice, "She's a Block of Wood?!?"
