As long as you're warm enough... we could tuck moss in with the sand, but if it's wet enough not to catch fire it might not be comfortable.

[Although lizards like getting wet, right? Either way, he sends along a mental image of his nest in the canopy since he isn't there. It's a frankly hilarious-looking mess of ripped-up blankets, moss, sticks, feathers and loose cotton that Firepaw worked very hard on. And for comparison he also sends along his old bed from home, a much more reasonable nest made mostly of moss, bracken and sticks.]

I can't imagine spending all my time sitting on rocks, but I guess there's always lizards on the Sunningrocks so it must be comfortable for them. Those are... a place in my old territory, with a bunch of flat rocks that get really warm when the sun hits them.
