|Complete 'Protect Farthy's snacks'.|
Protect Farthy's snacks was a mission in The Precursor Legacy that Jak and Daxter completed to obtain a power cell. Right after Jak rode the flut flut, he came across Boggy Billy whose pet hip hog Farthy had been scared away by lurkers. Jak had to protect his snacks from swamp rats so Farthy would come back home.
Accept the mission to begin this minigame. You'll then be in a fixed place with first person view on; you're only able to move it from left to right as well. The fixed position you're in is directly located on top of a bit of yellow eco, which instantly respawns right when your own charge runs out, meaning you can endlessly shoot fireballs.
Billy has placed five pieces of Farthy's food in front of you, which attracts the rats. They'll come in three waves, with more rats in each wave. The yellow eco fireballs automatically travel forwards and will strike any rat they come into contact with. If a rat eats one snack, you will lose and will ask "Do you want to play again?" After the last rat has been killed, Billy awards you with a power cell.
