Christmas Comes to Pac-Land feels like what Baudrillard was getting into when he started talking about simulacra. It is at once both clearly of a type directly inspired by the television Christmas specials of 30 years ago, but is written as if they didn't exist; unlike nearly every other Christmas special where Santa is taken for granted, Santa Claus has to explain who he is to the Pac people, who don't even have a concept of humans. (Why Santa is flying over Pac-Land to begin with, when it must therefore clearly not be part of his delivery route, is never addressed.)
The same thing is true of the Pac peoples' relationship to their source material, which has the same sort of looseness you'd expect of just about any story adaptation of a videogame, especially one from before the mid-90s, though Hanna-Barbera series this is part of eventually inspired both Pac-Land and Pac-Man 2.
The ghosts, the recurring villians of the series, do not so much steal Santa's toys, as is typical for the genre, as come upon them and immediately get distracted by plans to attack Pac-Man. They receive gifts in the end, perhaps out of recognition for never having attacked Santa directly and being no more than an easily-addressed nuisance to Pac-Man (as is the style of the series). As each ghost only is shown playing with a single toy when they come upon Santa's waylaid toys, they don't come across as greedy so much as just curious children who wanted to open their presents early.
The voice of Santa is the recognizable sort you're likely to have heard most of your life, as typically performed by Jim Cummings (the 'all the Disney roles' guy). Here, apparently, he is voiced not by Cummings, who was still a couple years out from his first professional voice roles, but by his Pooh-colleague Peter Cullen (who voiced Eeyore). I cannot explain to you how weird this is to think about, given how Cummings has become the go-to voice for Santa in both animated features and commercials.
