It's weird that people call Ghostly Adventures "westernised" - like, it certainly is with the slime jokes and faux-Pixarian blue CGI eyes, don't get me wrong, but of all the Pac-Man spin off media at that point it's probably the one that feels closest to the tone commonly associated with anime. A vast majority of the Pac-Man lineup, even including the arcade games, was developed in America, and a lot of what Pac-Fans accept as the "Pac-Man universe" was built off of classic sitcom tropes due to how influential Hanna Barbera's take on the universe was on the World games - even a lot of the Japanese-developed Pac games (like Pac-Man 2) were heavily inspired by American sensibilities. If anything we're seeing Pac-Man become Easternised as of Re-Pac (albeit more in the direction of Anpanman/Doraemon than Dragon Ball/Pokémon) rather than the usual other way around Japanese characters tend to go through.
