patients at the mental hospital who is obsessed with conspiracy theories. Schafer had been interested in knowing what went on inside the minds of those that believed in conspiracy theories, inspired by watching Capricorn One as a child. During a Double Fine dinner event, someone had uttered the line "I am the milkman, my milk is delicious.", which led Schafer to create the idea of Boyd, a milkman bent on conspiracy theories. Schafer then worked out a web of conspiracy theories, wanting the level to be a maze-like structure around those, tying that in to Boyd's backstory as a person who had been fired from many different jobs, partially inspired by a homeless person that Double Fine occasionally paid to help clean their office front. Schaefer had wanted the 1950s suburban vibe to the level as it would fit in with the spy theme from the same period. Artist Scott Campbell fleshed out these ideas, along with the featureless G-men modeled after the Spy vs. Spy characters. Peter Chan came up with the idea of vaulting the suburban setting into vertical spaces as to create a maze-like effect, which inspired the level designers and gameplay developers to create a level where the local gravity would change for Raz, thus allowing him to move across the warped setting that was created. The level's unique gameplay aspect, where Raz would need to give specific G-men a proper object as in point-and-click adventure games, was from gameplay developer Erik Robson as a means to take advantage of the inventory feature that they had given Raz. Schafer had wanted Wolpaw to write the lines for the G-men, but as he was too busy, Schafer ended up writing these himself. The art design crew included background artist Peter Chan and cartoonist Scott Campbell. Voice actor Richard Steven Horvitz, best known for his portrayal of Zim in the cult favorite animated series Invader Zim, provides the voice of Raz, the game's protagonist. Initially the team tried to bring in children to provide the voices for the main cast, similar to Peanuts cartoons, but struggled with their lack of acting experience. Schafer had selected Horvitz based on his audition tapes and ability to provide a wide range of vocal intonations on the spot, providing them with numerous takes to work with. Raz was originally conceived as an ostrich suffering from mental imbalance and multiple personalities. Tim Schafer
