They are Edward Platypus' four older brothers who bully their younger brother and are the reason Edward is bitter to the other Bean Scouts and are more successful than him.
They are shown to be ruthless, mean, rude, bossy, and arrogant as they bullied all the campers at Camp Kidney (including their younger brother Edward) until Edward stood up to them in the end.
They were revealed to have been campers in "O Brother, Who Art Thou". Cheesly ruled Camp Kidney with an iron fist and played tetherball with the campers just like they did with their younger brother Edward, and he and his brothers got away with it by acting sycophantic towards Slinkman. When they returned to camp, after having badly abused their younger brother Edward like a scapegoat, they intimidated, threatened, bullied, teased, and harassed all the other campers as before.
Their new reign of terror ended when their younger brother Edward returned in the long lost Rotten Cabin, and after running over Alpine, sent them running back home.
- They are the reason why Edward acts so bitter in the series, as their cruelty and poor treatment towards Edward caused him to develop insecurities he has carried throughout the series, and feel the need to establish dominance over the campers.
