So you basically just hit play and then the mouse starts drawing a big circle (although it's pretty much a bunch of circles inside of one another) so that it makes a spiral. The mouse draws this spiral shape in rainbow color. You can change the color he draws in with the "set pen color to" block. To make the mouse never stop, take out the "repeat" block and drag in a "forever" block, not connected to the rest of the code. Next, you will place the whole thing inside of the "forever" block.
