Click down on your mouse and move it to scratch the black and make a rainbow line, but don't move your cursor too fast or else instead of a rainbow line, it will be a rainbow trail of dots. Also, touchscreen will work on this. P.S, The thumbnail is a prank to @vasctch
This is my 2nd project on Scratch, so I am still working everything out, so if there are any bugs, tell me in the comments, and I will try to fix them or find a way to get past them. Like, Favorite, ad Enjoy the project. Pls follow me.
