The simple instruction is just to press the green flag in the top right corner of the screen to activate the animation of "The Unhappy Egg" and if you want to stop it in the middle of starting the animation press the bright red hexagon right next to the bright green flag.
This is a quick animation of an egg classically funny gag. which I'm sure everyone's dropped an egg before and there's egg yolk and shell everywhere. because it's sure happened to me.
