Arthur runs to the window, but doesn't see anything and when he comes back he sees that D.W. has eaten half of his brownie and Kate accidentally knocks his glass of milk over causing it to spill on the floor.

Arthur explains to the viewers that he sometimes wishes he was an only child because life would be easier and that he could use D.W. and Kate's room as his own library (he imagines using D.W. and Kate's room as his own library where he finds a yucky Princess Sneeze doll, but throws it away and continues reading, he also thinks that he might get more presents at Christmas, (he imagines at Christmas that all three of the stockings have his name on it), and finally he believes that with him being an only child he'd never have to compromise (he imagines himself sitting on the couch with Pal telling Pal that they're gonna watch The Bionic Bunny Special, then a Bionic Bunny rerun, and this his tape of his favorite Bionic Bunny episodes to which Pal barks in agreement.
