The game room offers another way out of the Manor. When you make
too much noise (i.e., barking) downstairs near Horace and Jasper,
you will get thrown into the game room. If you get thrown in the 
game room a fourth time, the door slams behind you and knocks the
pool rack loose. Get the balls back into the rack and move the 
rack by the door. Bark to summon Horace, who will open the door
and step on the balls! He will run into the wall with his backside
facing you. The Rhino head falls on Whizzer's head; when you click
on what's left of Horace, Whizzer will ram him and you will be 
outside!
