The player can drive on the overworld walls by driving up one of the outer ramps of the Thug Tug as fast as possible. Although the game will function normally when doing so, driving off it and into the void will crash the game. It's possible that this was an oversight by the developers.

The squires in the game have an unused animation that may have been planned for use when the player attacks one with the Patty Wagon. The squires do play a part of their animation, however, they simply disappear after they use their trumpets when the player hits them.
