Stop that mouse! Or else he will eat this sharp, creamy, hard piece of cheddar with sunflower seeds and juicy red/purple grapes that you are saving for yourself. (heeheehee) (if you have any allergies, then sorry, I didn't know. Just play along.) Simply move your mouse (pointer) around to make the food move around to keep it away from the mouse (animal). Got that? No? Okay, I'll make it shorter. Move mouse (pointer), then food moves, mouse (animal) will chase food, don't let the mouse (animal) eat the food. Okay? Good. Now go play! Hit that green flag! Actually, don't hit it. You'll get into trouble for that. Just click it. There you go. Now go play!
I was messing around on Scratch, and this idea came to me, and I just HAD to make it. So here you go.
