located next to the sky tower is a pool with drivers. You tell them which area to pick up oysters from and they grab a hand full, and you pick out one. They can come in five different colors. Pink, white, black, blue, green. The cost is about 15$ per pearl.
They also do pearls like that at japan in epcot, little stand at DTD near the pin store. There might be one more someplace else at disney, all in the 15$ range.
The horse barn is located in the back right, above the shamu stadium, and to the right of Sharks. It used to house the clydsdale horses, and one donkey. Every day they used to pull the bud wagon through the park, like you would see in the superbowl commercials. The bud horses are gone, and some other outside group brings in a few purserons, however you spell it. The do a little talk in the day time, and you can still have your picture taken with a horse for a fee.
Right next to it is the terrace, which is another quick service. This is where they used to do free beer tasting. Which went out before busch left the parks.
