Lifty

Lifty is one of the main characters of Happy Tree Friends. He's also a boss in Deadeye Derby, along with Shifty, both together making a singular boss.

Character Bio
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). They also hunt for treasure, ransack houses, or do anything to get rich quick. They mostly steal from Lumpy (in Meat Me for Lunch they steal meat from Lumpy'sdeli mart, in Milkin' It they steal a cow from Lumpy's farm, in Concrete Solution they steal his wallet, and in Junk in the Trunk they abduct his pet elephant). They probably rob Lumpy so frequently because his lack of intelligence and common sense makes him an easy target.

Happy Tree Friends Adventures 6
At the start of Happy Tree Friends Adventures 6, Princess Allay and Brandy are walking together until Bowser, Lifty, and Shifty warp behind them. Bowser commands Shifty to capture the princess. Brandy tries to stop them, but is immobilized by Lifty. The three villains then take the princess and Brandy away while leaving a ransom note that is later found by Neena.

Lifty and his brother are later seen with Bowser and Pete in a cutscene after the penultimate level.
