Well now I just want to help keep you two from dying horribly.

Check the far corner if you can. When we stayed there we left the wrappings from our food there, some of it might burn. There might even be a stray piece of paper or two, Frisk had paper to draw on and they may have left behind some.

Is it affected at all by the light from the tablets, or is it only natural light that keeps it away?
