Click Green Flag, Hover Mouse Cursor over the Scratch Cat to Stop him. Click off the cat to start it moving. Drag the cat where you want it. (he will turn blue).
This is if you do not want to use the Stop Sign but want to Stop the Scratch Cat and want to set the timer to zero and want the timer to count up when the cat is moving. The Stop Sign is unused in this and will just stop all code and start the timer like it usually does.
