Gohan was firmly planted by the campfire, roasting a marshmallow on a stick. He may not have known what s'mores were back when he was first here, but after ten years, he definitely figured it out. Of course, part of the reason why he was cooking s'mores instead of something else was because they were in a cavern in the space future, both not lending themselves well to finding meat to cook...

But s'mores were still nice. He'd already eaten a couple. Maybe someone else wanted some?
