Male Species: Human Occupation: Office worker (fired) -> Scientist Famous line: MAC!!!!!!!!!!! RONI!!!!!!!!!!!! Constant sufferer + Big-hearted man [Description] A genius but somewhat lacking inventor. He is very authoritative, so Mac and Roni are scared of him, but in reality, he's the one who gets pranked every time lol. He's basically the Go Gil-dong of the 2020s.

Male Species: Penguin A fastidious, troublemaking assistant. He's quite rebellious and often messes with Albert's inventions (very strictly). When cooking, he accidentally added 200 servings of hot sauce, turning the soup into literal magma... (hot enough to melt cookies...) He doesn't feel the heat even when eating spicy food. (Roni should basically be Korean at this point.) He adds 'Quack' to the end of every sentence. (When screaming: "QUAAAAAACK!!!!!!!!!!!!!!!!!!") He is aware of the trouble he causes. He wears a jumpsuit.

Gender: Unknown (Robot) A robot invented by Albert. He seems to handle chores in the lab, and his cleaning skills, cooking, and crisis management abilities are quite impressive. However, just like Albert, he is frequently victimized by Mac and Roni's antics. Currently under repair after Roni tripped while bringing water and splashed him.
