Pid, so loyal to the government of Gola, is disgusted by these statements and sneaks into the atomic power installation himself. Right before he activates the displacer in the reactor room, he sees a bird fly past the window, and realizes that this animal has a shape that goes above and beyond his wants and needs. Disregarding all that he has just said and accused his friends of, he jumps out of the window and morphs into the shape of a bird, abandoning the assignment he was given, and deciding to live in the shape most desirable to him.
