I think you may be confused what is pac-man. The species of
pacman is a fictional species called a pac person or pac people.
Just like humans in real life but the word pac in their world, so
they call them pac people or person. In the pac man wiki it says
that pac man's species is a pac person. In the pac man world series
pac man owns a pac dog and is yellow just like the other pac
people. The name of his pac dog is Chomp or either Chompy. These
are the list of pac people that exist: Pac-man, Mrs pac man, baby
pacman, and that's all I can think of. In pac man and the ghostly
adventures the new pac man TV show there are all kinds of pac
people that appeared in the show. In the video game series back
then they were all yellow. But in pac man and the ghostly
adventures there were different all colored pac people. In the show
pac man and the ghostly adventures it's says pac-man feels alone
because he was the only yellow one since pac man world war
ended.
