"Are you scared of the dark? Did you know that when the clock strikes twelve, that's when the midnight monsters come out? Johnny Boo knows, but that won't stop him from skateboarding on the back of a wild Tiger and plucking pumpkin ice cream from the gaping maw of a Spooky Tree. He does it all to impress Susie Boom, the cute little girl ghost who lives on the moon. Hopefully she's watching everything with her telescope!"--
