101 Dalmatians - Escape from De Vil Manor trainer

Rooftop Over Kitchen
Go to young Cruella's bedroom then click on the bedroom to go the rooftop.
To plug the hole in the roof, click on the flowerpot. Now you can click on
the Trellis on the other side of the roof. Once you have done that, you
are on your way to the attic.

Attic
There is a way out of the Manor in this room. You must go up the pull-down
stairs in the ceiling. To reach the stairs, the trunk must be moved below
them. To move the trunk, it must be emptied. The trunk opens with the
combination to the lock. The combination is on the right-hand wall in
Nanny's room that is revealed behind a flap of wallpaper from a breeze
when the window is opened. You can open the window when you jump from
the bed to the windowsill. Click on the trunk and the combination will
automatically be entered.

Game Room
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 4th
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!
