Here, the items are called a “Sharp Shooter,” “Hat-Off Cowboy,” and “Acrobatic Alien,” and they are named such to let you know what their animations do. The Sharp Shooter can shoot fire, the Hat-Off Cowboy can take off his hat and smile at you, while the Acrobatic Alien can perform tricks in the water.
All three items are limited edition, meaning that they are limited in their quantity of availability in the store. As of this writing, the alien is the most limited of the three, with 5200 units left, while the other two are available to over 6200 users.
In terms of prices, you’ll pay either 60 Pearls or 50 Facebook Credits ($5) for the Sharp Shooter, 42 Pearls or 35 Facebook Credits for the Hat-Off Cowboy, and 36 Pearls or 30 Facebook Credits for the Acrobatic Alien.
