 After trying many different foods, Cass sees that her mother is gone.Outside, she reads the note given to her by the waiter from Señor Hugo, which demands the Tuning Fork in return for her mother.Later at the fire station, Cass and her friends search for the Tuning Fork, as they were told earlier by Mr. Wallace that by now the Fork, which was originally possessed by the Aztec boy "Caca Boy", would probably have ended up in a junk shop, and assumed that the junk shop he was talking about could only be Cass's grandfather's home.
