Frozen Shinies: The Emperor Penguin's Nephew

From BoardGameGeek:

The Emperor Penguin is a connoisseur of fine jewelry. His excitable but somewhat dim nephew, on the other hand, can't see why you'd prefer an emerald to two pointy sticks. Two is *twice as much* as one! In Frozen Shinies, you're a royal helper racing between penguin trading shops, exchanging treasures not to get the most valuable things, but simply to get the most. Can you trade a diamond for a spool of thread, a handful of coins, and a floppy hat? The Emperor Penguin's Nephew will be delighted! Each card has a value from 1 to 14, and most cards have a power. Place a card in the front of one stack and take cards of the same value from the front of another stack. If the values aren't quite identical, "make change" with tasty fish. Or, use a card's power to manipulate the stacks in other ways. When only one stack remains, the player with the most cards wins! -description from the publisher
