McGregor's dog, McMutt, has his feelings hurt when the Little Ghosts tell him that he should go away and hide. He doesn't understand that Henry, George, Lucy and Edward are only playing a game of hide and seek, and that it's his turn. They look for McMutt everywhere- twice- but he's nowhere to be seen. A trail of biscuits is only useful in finding Edward, who isn't even lost, and a "dog" whistle is only successful in finding some bats. Finally, McGregor suggests looking in his kennel. Oh, dear, no one thought of that, but it'll take more than a dog biscuit to bring McMutt out.
