Frozen Shinies: The Emperor Penguin's Nephew

The Emperor Penguin’s nephew knows treasure is good, but can’t for the life of him figure out why you wouldn’t want more treasure if you can get it. So you’re a royal helper, trading frantically not to acquire the most valuable treasures, but simply to get as many as you can. Can you trade a diamond for a pointy stick, a fancy shell, and a hat? Three things are way better than one crummy old thing - the Emperor Penguin’s nephew will be delighted!
