Curtis (Fallout 2)

Curtis is a child in the Vault City courtyard who has lost his Mr. Nixon doll. The doll is located behind a wall on the right side of the bar. Return the doll to him and listen to him speak to it for a while. He will make mention of burying his fathers wrench in a pile of rocks behind the bar. Search the rocks to locate the wrench (which can be used later as part of a quest). The wrench will NOT appear until you've heard Curtis mention it while speaking to his Mr Nixon doll. (Note: The doll itself looks like a small box on the ground so it can be easy to miss if you don't know where to look)
