Poke the backpack.

From Create Your Own Story

With a tentative finger you slow reach up and poke at the monstrosity sinking its teeth into your face. "Uh, mister?" You ask.

The backpack goes on biting you. Well you're screwed.

• Pull the blanket over your face and backpack and go back to sleep.
• Try to talk the backpack out of eating your face.
• Give an unnecessary fart.
