Steak Guy is a giant talking steak that first appeared in Episode 5. He taught about healthy eating. He appears in Episode 6, but only for a few seconds.
Steak guy is a giant uncooked steak with white gloves, red shoes, and a small tuft of brown hair with a chefs hat. His eyes are lopsided, his nose is large and in the center of his face, but his mouth is off to the side of his face. He carries a meat fork in his hand, and uses it to either illustrate his point, or prod at the others.

- Steak Guy calls healthy foods unhealthy, likely due to Roy's poor lessons.
- Steak Guy calls cooked meats bad, even though he's a steak himself.
- Steak Guy considers bread, cream, white sauce, and aspic the only healthy foods, but for unknown reasons, he later states that white sauce will make teeth go grey. This shows that the teachers contradict themselves often.
