The model for Pac-Man when walking around the Museum Hub contains 8 different face models. Only 3 of these are used in the final game, with another 3 appearing to be placeholders, and the last 2 resembling the hurt and dying animations from Pac-Man World. In addition, an unused idle animation used in Pac-Man World can be found in the game’s files, depicting Pac-Man juggling and then eating pellets. These would later be utilized in the 2022 remake Pac-Man World Re-Pac.
