Purple is a pretty color - I think most people would agree. But, when they have menacing looks on their faces, they must go, and that's what you have to do in this game. The purple shapes have invaded this land that is pleasing to look at. The purple invaders are so menacing that some of them have their tongues sticking out at you. They're secretly laughing at you because you can't click to remove them, but the joke is on the purple invaders - you can click the blue objects to get rid of them.
