After a few hours being gone, you open your door to your room and the first thing you see is your plain, black, school backpack on the ground exactly where you left him last. He looks normal and he is leaning against the wall with his floppy straps laying against him. He is making little low chitters since he is content. His chest or front area of him is moving in and out as he breathes.

He looks at you and immediately lets out a deep, low growl in a friendly way.
