Snotty Boy is mean, dim-witted, mean-sprited, sadistic, abusive, annoying, spoiled and obnoxious. Snotty Boy constantly boasts and arrogantly brags about having "skills" that he clearly doesn't have (such as possessing Karate skills, psychic abilities, insults, and salsa dance moves). He annoys everyone, except Mrs. Beady, whom he acts sweet and innocently to until she is out of earshot. Snotty Boy's range of insults is rather limited and unimaginative, usually just resorting to "stinky," "stupid," or other basic insults.
He enjoys torturing the animals, his best friends, and Mr. Beady, which is the basis of the hatred by them. However, he only bullies his uncle when Mrs. Beady isn't around. He is also rude towards his parents and often mocks them as well.
In the premiere episode of the series, Snotty Boy is given the chore of watching the animals when the Farmer has to leave for the weekend to a non-existent event called "TurnipCon". Instead, he takes to tormenting and hurting them. The animals seek revenge on Snotty Boy by pummeling him with eggs, stuffing him inside a bundle of hay, and then springing him into the air. His uncle then removes all the hay off of Snotty Boy with a chainsaw.
Snotty Boy had a large pet snake named Stinky McStupidhead, whom he mistreated and tried to feed Pip to. In the end, Pip was rescued and Snotty Boy was outwitted by Otis and his best friends by having his pants pulled down, being given an electric shock, and finally being swallowed by the enraged Stinky. Apparently, the removal from Stinky was extremely painful.
In "Some Like It Snotty," Otis disguised himself as a girl and ended up dating Snotty Boy. Soon, he discovered that Snotty Boy was two-timing him and was also dating a horse, who was dressed as a woman.
In the episode "Snotty and Snottier," it is revealed that he has an older cousin called Phlegmy Boy, who is worse than him. Phlegmy Boy's abuse of Snotty Boy could possibly be the reason for Snotty Boy's bullying nature.
