A stand of apples catches your attention. Red, yellow, green, no bruises, perfect shapes. They look fantastic. Are they really organic? Organic food doesn't usually look this good. You glance at the sign. Yes, they are organic. And they're surprisingly affordable, too! It also looks like the sign is claiming the apples are good for your skin. You've been having some issues with your skin lately, so you wouldn't mind getting something to help that. In short, you'd be a fool not to get some apples.
If you had actually read the sign, rather than skimmed it briefly, you would have found out that when it said "new skin", it meant it literally, not figuratively. The apples will change your race. Each color has two different possible race changes, depending upon whether it's eaten peeled or not.
After a few moments of consideration, you figure out which color you want. You begin to select your apples. Like when you first looked at the stand, there aren't many that look bad, so you can pick any color you want.
