The case of Clue's circus caper

Our dog, clue, is supposed to be a circus clow, but somebody wants to stop her. Is it Flip the Clown, who doesn't want another clown in the show? Or Galloping Gracie, who is mad at Clue for ripping up her favorite costume? <p>Mary-Kate and I have to find out -- or Clue could be in real trouble!
