🎪 Things to try

Nobody reads a feature list to find out a crab can be thrown.

Have a go. Every one of these is a setting: turn up the ones you like and switch off any you don't. The pals, the typing and the pranks stay off until you turn them on.

Download for Windows See it all

Shellby hops onto a Notepad title bar, hangs on while it's dragged, then is shaken off and lands dizzy — **Throw him at a title bar**He climbs on. Drag the window and he hangs on; shake it and off he goes.⚙️ Settings → Shellby → Climbing onto your windows

Shellby sits on a window; it closes under him, he hangs in mid-air, then falls — **Close the window under him**A beat in mid-air, a look down, and down he goes.⚙️ Settings → Shellby → Climbing onto your windows

Shellby is thrown at the left edge of the screen, sticks to it and climbs up — **Throw him hard at the side**He sticks to the edge of the screen, then climbs.⚙️ Settings → Shellby → Climbing the edges of the screen

Shellby is thrown up among his four little pals, who scatter when he lands — **Throw him among his pals**They keep him company on the floor, and scatter when he lands.⚙️ Settings → Shellby → Pals on the floor (off until you pick some)

Text is typed into Notepad while Shellby taps along, then says new record: 180 wpm — **Type fast**He taps along on a little keyboard, then tells you how fast that was.⚙️ Settings → Around you → Typing along (off until you turn it on)

Shellby creeps up on the mouse cursor, pounces, misses, and says meant to do that — **Leave your cursor near him**He pounces on it. And misses.⚙️ Settings → Shellby → How much he talks

And a few more

Do this, and he…

Do this	And he…	Switch
Flick him while you drag him	tumbles across the screen, bonks off the edges and lands on the taskbar	always on: you started it
Throw him at the top of the screen	sticks to it and walks along it upside down, legs swinging	Settings → Shellby → Climbing the edges of the screen
Rub the mouse back and forth over him	gets petted, and you two grow a little closer	always on
Play some music	puts his headphones on	Settings → Around you → Listening along
Right-click → Play → Dig for treasure	digs, and every so often holds up a find	only when you ask
Right-click → Play → Hide and seek	burrows into the sand and pops up behind one of your windows	only when you ask
Right-click → Play → Fetch	waits for you to throw the pebble, scuttles after it and brings it back	only when you ask
Turn on Mischief (if you dare)	pinches your cursor, shoves a window and drags notes onto your desktop	Settings → Shellby → Mischief (off until you turn it on)
