Just press the green flag and the troll will do the rest
I don't know what to say but because I am dumb I will tell you the code. First on a new tab search: Toll face then, download it then go and into a new project and then, you hover over "new sprite" and go to upload sprite and then click the troll face now, you go into the sprite and drag a " Until green flag clicked" then drag a forever block and in the forever block, put a "Move 10 steps" and after that you put a "If on edge bounce" then after the if on edge bounce block you put a "Go to random position" and your done just press the green flag and you have your own crazy troll face. (I am a bad coder, don't blame me)
