The crab should move when you press the arrow keys, and change to the colour of any circle it touches. Debug the code to find 3 errors. Hint: 1. Does it go in the right direction when you press the arrow keys? 2. Does it turn the correct colour (costume) when it touches each coloured circle? 3. Why doesn't it change when it touches a green circle?
