Chubb Munch

Chubb Munch, the four times he is seen throughout the series. He is always conveniently sitting front of the Teacher's Lounge/Office. In the games, his favourite desserts seem to be cookies and pudding, though the range of overly caloric delicacies he devours is unclear. Chubb is also one of the students of the school who is a marine animal. We know this because Marinette Dupain-Cheng counted him in Animal school developer commentary. Chubb is one of the few characters that is real and not from Phil's dreams as he was shown in Animal School.

Family
Chubb's mother is Mrs. Munch, the lunch lady at Animal High School in the third game of the series. According to the Animal School 4 special features, she divorced her husband because she "realized he was a terrible husband"

Chubb's father is Mr. Munch, who plotted to kill everyone his wife knew out of the rage of their separation. Upon realizing he only knew of one person his wife had been associated with in any way, he made a plan solely to murder that one person, and this person happened to be Phil Eggtree. He dug a hole into a lava stream and designed Zoo University to sit on top of that hole. Then he requested to be a teacher at that school and strategically arranged a circle of remote-controlled explosives in an area of his classroom floor that was made not to be as thick as the rest of the floor. The explosives were detonated in Animal School 4, and his endeavour to murder Phil was successful.

In reality, Chubb's mother and father probably are not exactly as they seem, as they are only seen in what is revealed eventually to be Phil's lifelike dream fed to him in a space station. The human Diz altered the dreams being transmitted so that Mr. Munch would go about killing Phil, meaning it is possible he and his wife never actually had any ill will toward anyone. Chubb is also shown to not mind his insults, even be entertained by them.

Some may debate that his last name was made up, along with the teachers. As the aliens didn't know about earth culture completely and neither did the students, the one in a million chance that children and teachers have ironic names may have been taken as a certainty, leading to several pun-like names and strange or ironic behaviours. This is also proven by the fact that in real life Richy is a pre-teen jock/bully who has no interest in collecting buttons due to the fact that they only met once and they would not have much information to base him on.

Trivia
