- "Giant Consequences" (Background)
- It was confirmed by Eric Stirpe that Bob's appearance is randomized--sometimes having a Caucasian skin-tone with blond hair, and another version with a brown skin-tone and black hair. 
- This means that Bob is the only character in the game that can have more than one skin tone regardless of the players choices
- There is another character in "Access Denied" with the same name: "Bob."
- Bob and Reuben are the the only characters to have the same name as another character. (Reuben (Human) and Bob from "Access Denied")
