Congratulations! You've been awarded a King's Credit! Visit the royal prize shop to claim a prize of your choice, or keep saving up to redeem greater rewards!
King's Credits are awarded during the King's Giveaway, and are the only currency accepted in the Prize Shoppe. They can be obtained by catching prize mice: Treasurer, Snooty, or High Roller. A Hunter with a higher Prize Power is more likely to encounter a prize mice.
