I've had a word with the pygmy hogs, they're top notch nest builders, and the capybara, joinery and carpentry. They think they can section off a piece of one of the hot springs. Put in a submerged floor, at the right depth for gerbils, decking, changing rooms and saunas, and a hot mud pool (that was the pig's idea). We've inflated some tribbles for bath cushions and floats, flattened some others to use as rugs for the gerbils to relax on. I think some gerbils want to work as masseurs, wherever they're needed, if something needs rubbing, they'll rub it. They're loving the empty* toilet rolls.
*is empty the right word? Surely they're always empty. Perhaps peeled, stripped, skinned?
