Picket

Picket is an Al Bhed Watcher, who resides in Bikanel with Nhadala and her crew, seen in Final Fantasy X-2. Although Picket is technically genderless, it has a male personality, as it once flirted with Yuna. Because Picket is an Al Bhed Machina, it is fluent in the Spiran and Al Bhed languages.

Purpose
Picket is a surveyor of the vast desert region, it normally flies around the island to see if anyone had gotten lost within Bikanel's sands. If there are people who have gotten lost within the desert and/or have fallen from dehydration, Picket alerts the Al Bhed diggers of the person's/group's location. It even has the ability to detect unidentified objects that might appear while digging in the sands.

This ability of Picket's is seen in Chapter 1, when Rikku manages to get the Gullwings lost in the desert because she could not locate the campsite. The Gullwings soon fell to dehydration after walking a ways, and Picket happened to be there. According to Picket, the Gullwings were located at region B-5 of the desert.

Picket is also the escort of the Gullwings when they decide to go digging. However, the Gullwings are under a time limit. Early on, this limit is 10 seconds, but later, it is made 30. After the time has expired, Yuna will collapse from dehydration, and anything found during the dig will be abandoned.
