Dave loves his cave. It's decorated EXACTLY the way he likes it. Outside there's a lovely spot for a fire and the grass is always green. But, Dave is unhappy. What if there might be an even better cave out there? He sets off in search of a new cave, but it turns out that nowhere is quite as good as home.
Meet Dave, Caveman Dave. Dave live in cave. Dave cave perfect.
But Dave not happy... Dave want new cave.
