Prison Pete is a random event, which takes place in ScapeRune. The player is teleported by Evil Bob (a cat) to a prison while shouting "Aaaarrrrgh!" where they must pop three correct balloon animals which contain the key. Each key is handed to Prison Pete, who tries it out on the doors, and says if it worked or not. You know which balloon animal to pop by pulling a lever which shows you a picture of the correct animal.
