BETRAYUS! HMPS!, Pac darling, stop fighting with your father, calm down, it's not at all disconcerting that you act that way.
Inspired by your furry friend :3
Monny's new design and the only design closest to the cannon also because it is the inspiration of Hanna Barbera, that there is a possibility that Pac will have a sister in any future (Despite the Rmk of Pac-World, Pac-sis and Pac -boy)
Envelopes, the word of the Orb is defined by the yellow cells of the individual character that generates a source of power that is activated by eating the berries, for that reason Pacster shines when eating a power berry, because its cellular flow generates a source of power that It prevents it from generating energy by calling itself yellow cells. It is like squeezing a lemon full of energy with each layer of the lemon's skin to know that it is more sour until you obtain its flow of power, thus defining itself as Races of the Yellow Orbs it is not necessary to define as a surname knowing that it is by races for its inhabits the yellow living being and that is based in several ways on Japanese Science Fiction Fantasy (ALTHOUGH THE SERIES EVERYTHING PUT PAC TO EVERYTHING AS OR PHYSICAL OBJECTS AS NAME PAC-WORLD)
On the other hand, about Pacster and his last name, the most comforting thing would be to respect the original genre of the Pac-Man 80's video game industry, the Coconut Eater, knowing that patga and his character reset on Coconuts (<- known as Pac-Dots) to Berry are very different, but the word Pac has more than just one meaning of not only Puck-man. Japanese Onomatopoeia pakkuman is about chewing and making sound that is produced when opening and closing the mouth of the WAKA WAKA. Paku Paku Taberu! It would be a good surname because it makes waka waka, not only that if it did not give meaning to its name to Pac (pakku originally) but because of its product of video games referring to food (<- logical) by the creator Toru Iwatani When Namco released the game though, they did not name it after the character. Instead it was called Puck Man, presumably due to the similarity in Japanese pronunciation and his resemblance to a hockey puck (though nobody really knows LOL).
Pac-man, Puck-man, Pakku-man have different meanings behind the Namco studio and also because of their genre of video games, different than the other mentions but it will always be definitive with Pac.
In my opinion, this is how I conclude in this research on their surnames:
Zac-uck Paku Taberu
Pac-ster Paku Taberu
Sunny Paku Sunshine
Monny Paku Taberu
