Bait items are items that cannot be obtained through playing normally, but can be obtained through cheating programs. The aim of a bait item is to trick the cheater into getting the item (and taking advantage of it further if they wish). Once the item is in the inventory, the cheater is banned for at least 72 hours, hence the name "bait item".
If a bait item is obtained client side, the item will not be on the penguin unless it belongs to a special penguin, though all (except Yarr, Gray, and the items that make the player card penguin pose, like Rockhopper's hat) will not show up on the player card (example: Cadence's shoes.)
