Then ride the self-rising flour up to the windows and peer out, planning your route once you're out of the building. Open the curtains if necessary... But if so, hurry.
Drop the casserole dish, then return to the ground. Acquire large shard and several throwing shards. Cut hand on shard to make sure they're sharp.
Remove 2 of the stove elements and bend them into long thick "wires". Attach them to opposite corners of the door.
Start baking the flour and butter on one of the remaining elements. Yes, directly on it.
Pour sugar into the milk to make nonchocolate milk survival drink.

You probably only need a couple of Notches of space, really. Crawl under the door, steal the guards' everything, escape.
If accosted, pretend to be a birthday cake stripper.
Find a bar
