During beta testing, Billy Picaroon was an Accessory Vendor. Briefly in the development of the game, he was known as the Racing Accessory Vendor. In early beta testing, he had Bob's textures, but with black gloves and a black bandanna and was located in front of a small shack between Keelhaul Canyon and Rudder Bumpsteer's booth. In mid-beta testing, his White First Mate's Shirt had a classic design and his black bandana was a darker shade.
The early beta version of Billy Picaroon was spawned by a Mythran at Red Blocks on January 30, 2012, but acted as a Brick Vendor much like his finalized version.
