Lifty

Lifty and his brother Shifty are two green kleptomaniac raccoon identical twin brothers with dark green mask-like markings around their eyes. They frequently steal merchandise and produce from the other Happy Tree Friends (thus their names), as well as treasure hunting, ransacking houses or anything to get rich quick with the exception of Flaky, Lammy, Cro-Marmot, and Splendid. They mostly steal from Lumpy. They probably rob Lumpy so frequently because his lack of intelligence and common sense makes him an easy target.
