After dark: finish an episode and twelve harder rooms open under it — the same creatures and hazards at full strength, on bigger floors, with longer goals. Seventy-two new rooms in all. The owl's light now has straight edges, and she catches anybody who stops in it. Nine story rooms in the kitchen, the coop and the attic that random tapping could win are replaced with rooms it cannot. And the fox no longer sees behind him: stop at his tail and you are safe. Adverts come round less often.

A fifth episode: the barn. It rained all night, the creek is over its banks and the water comes in a row at a time. Piglets cannot swim; ducks can, and a duck in the water is a thing to lean on. Twenty new rooms, two new films, and the barn in Endless and today's room.

Rooms get harder as you go: the easy late rooms are replaced and every episode is re-sorted. The dog is on the hens' side: stop beside him and the fox cannot reach you. The way home sits at the top of the room picker, the ad hint says so, and Settings shows the build number.
