Herd the moles into their hole was a mission that Jak and Daxter completed to obtain a power cell in The Precursor Legacy. A group of lightning moles had been scared out of their home by lurkers, until Jak chased them back in after a request from the Geologist. It is temporarily named Return to the Geologist once you have herded all the moles into their home, but without having visited the Geologist for the reward.
