Drof, sees all caveman lie down on ground. He sits around a while.
When all becomes quiet he hits something a few times making a hell of a racket. Then he lies down and falls asleep, happily mumbling something like: "big bakdakaka".
Spid display his smart caveman brain! Spid have great idea, now if only Spid can remember why he stay wake while other cavemen all sleeping...
Spid manage. Spid amuse self by watch Ourgh sleep run. Ourgh wander back into trees; probably have to find him when sun come.
Spid laughing at Ourgh when see something moving. Two rock things! Two rock things crawl into camp near sleeping cavemen. Rock things hiss, Spid not like. Spid yell for other cavemen wake up.
