Herd the yakows into their pen (intermediately assigned as Return to the Farmer) is a mission in The Precursor Legacy that Jak and Daxter complete to earn a power cell. The Farmer's yakows got out of their pen after some "strange creatures" (presumably lurkers) tried to steal them some time earlier.[1] Jak then herded them back into the pen in exchange for a power cell.
Completion of this mission in the PlayStation 3, PlayStation Vita, and PlayStation 4 versions of The Precursor Legacy will unlock the bronze trophy Yee Haw!
Walkthrough[]
Five yakows will be scattered across the beach in front of the Farmer's hut. To herd a yakow back into the pen, simply put it between the pen and yourself. The yakow will then move away from you, meaning you must travel along with it strategically such that it eventually walks into the pen.
You can kick or punch the yakow to cause it to swiftly change directions, though doing so otherwise has little effect on the speed of the yakow.
The pen, which is next to the Farmer's house, has a gap in the fence, in which the yakows will automatically enter once nearby. Once inside, a yakow will not leave the pen afterwards. After herding all five yakows to the pen, return to the Farmer to receive a power cell.
