This is what he looks like.
Lean-Mr. Krabs is the result of Mr. Krabs overdosing on lean regularly instead of ketamine, due to how the cough syrup found in lean makes lean more addictive than ketamine. Lean-Mr. Krabs resembles Mr. Krabs, but instead with a purple pigment caused from his obsession with lean.
He has an extremely unhealthy obsession with lean, and loves lean far more than he would ever love money. He chugs 3,000,000 gallons of lean every hour, which is how he gained his purple pigment. Lean-Mr. Krabs became one of Wario's lean minions eventually due to how he felt the need to be one; this is a minor effect of lean whenever it is consumed.
Lean-Mr. Krabs possesses the ability to infect people with lean simply just by pinching them with his lean-filled claws, due to how his bloodstreams, bones and flesh are literally made out of none other than lean. He can also shoot lean-filled lasers out of his big eyes, similar to that of Twtll. He can also pollute entire oceans with lean, which is how the Lean Ocean came to be. Lean-Mr. Krabs is currently planning to pollute Bikini Bottom with lean.
