You have 40 seconds to clean the gross stuff. Use ten of those seconds to decide your difficulty using the slider bar. The first high score is 80 (set by me) try to beat it, it's not hard. Put your device on a table or countertop. Click the green flag and set your difficulty level. To wipe away the gross stuff move your hands around the screen. Good Luck!
I used a "how-to make stuff on scratch" book to do this. It was meant for 2.0 but it still worked. Just look up "Coding Projects In Scratch" It will come up. It's the one with two sharks a birthday cake and a few other things on the cover.
