Five rocks in the scene are secret triggers. Tap one and it glows, and an animal appears in the part of the scene that rock controls. Tap the same rock again to send the animal away. Press and hold any of them to open the test panel.

What each rock does

1. Big rock, far left Far shore under the mountains

   Deer walking out of the trees and back in; doe drinking (spring to fall); elk (fall, winter); bear walking the shoreline (spring to fall, daytime); wolf running (fall, winter); wolf howling (fall and winter nights).

2. Rock next to it Right bank with the three pines

   Deer stepping out from behind a pine trunk (a buck in winter); hawk on a pine top (spring to fall, daytime); owl on a pine top at night, and a white snowy owl in winter, day or night.

3. Small rock beside the green bush Right bank

   Hare hopping along the right bank in front of the pines, white in winter.

4. Big rock under the tree The lake

   Fisherman drifting across the lake and out of sight behind the right bank (spring to fall), with a lantern at night.

5. Small rock above it Fox and chipmunk

   Fox trotting out from behind the big tree (or a right-bank pine) to look about and sniff, or a chipmunk popping up behind the small rock (chipmunk daytime, not in winter).

Every animal, and the word to test it

The note under each link says when that animal is about; the link opens a season where it shows. Its last word also works on its own, whatever the season: ?foreelk. Two are called up by touch instead: a fish jumps when you tap or hold the lake (spring, summer), and the eagle catches it when you hold the lake for about 2.5 seconds (spring to fall, by day; also “Eagle catches a fish” in the test panel). With a mouse, rings follow the pointer across the lake. The weather comes in three levels: rain is ?drizzle, ?shower, ?tempest (or ?storm); in winter snow is ?flurries, ?snow, ?blizzard. A storm also blows through now and then on its own. And somewhere on the lake is a way to a getaway: tap the fisherman’s paper boat (spring to fall) and it sails you to a tropical beach; ?beach goes straight there.

Scene effects that come on by themselves: fireflies at night (a different colour each season), Marley’s glowing collar at night, the lamp inside the tent at night, and wind gusts that start 5 seconds after a season settles.

Test panel

Press and hold any trigger rock for about a second, or add ?wildlife to the address. A small panel opens in the bottom-right corner listing every animal (use ⇄ to move it to the other side and – to fold it away): click one to play it, click again to send it away. “Any season / time of day” plays everything regardless of season; “Send everyone away” clears the scene.

Other hidden spots

Tap	What happens
Open lake	A fish jumps where you tapped (a ripple in winter)
Far shore	One of the far-shore animals
Right-bank pines	Hawk, owl, or the deer from behind a pine
The big tree’s leaves	Squirrel on the branch
Left bank grass	Hare (on the right bank)
Foreground grass	A hare hops across, sits up and sniffs (white in winter)
The sun	An eagle high over the mountains
The moon	A howling wolf or an owl

On their own

About every 30 to 60 seconds one visitor arrives by itself, chosen to suit the season and whether it is day or night. The fisherman crosses the lake every two to three minutes in spring, summer and fall. Nothing plays while the scene is scrolled away, the tab is hidden, or a season change is running.

?summer+night	Opens on a season and time of day: summer, fall, winter, spring (or books, web, workshop, lab for the Play tab) with day or night (nightmode or darkmode also work; night turns the whole page dark). Combine with +
?fall+fox	Also brings in an animal. Every animal’s word is in the list above
Tap the tent	Marley comes out to sniff about
Tap the hero tree trunk	A close-up: a grizzly, bull elk, doe, buck, wolf or Marley peeks in from the right, looks about and backs away
Tap the grass at the lower left, under the headline	A small close-up: a fox, hare, chipmunk or squirrel steps up and sniffs toward the headline
Tap the grass by the hero tree	A big animal visits up close: doe or buck, elk, bear, wolf or fox
?play	Plays the whole year
Hold on the lake, then let go	The longer you hold (up to about 2.5 s), the higher the fish jumps
Hold on the lake until an eagle appears, then let go at full charge	Daytime, not winter: the eagle circles overhead while you hold, then swoops in and catches the fish at the top of its leap. Let go early and it glides off

On phones the hero button sits over rocks 1 and 2, so those two work on tablets and computers.
