Attack of the Gnomes

I'm in a large dilapidated house, and it's my job to strategically place minuscule, yet fully functional, cannons about the house to defend against an imminent attack by tiny, gnome-like creatures. The gnomes, about the size and shape of eggs, appear utterly benign. I soon realize that they are entering through a particular window, so I abandon the cannons and work on building a wall in front of the window to block their point of entry. For neglecting my cannon duty, I am reprimanded by a portly military gentleman.

Seriously considering the possibility that I may perish in the ensuing battle, I decide to make a break for it -- either by hiding in the attic or leaving the house entirely.
