Lefty is a character from the 2007 Disney animated film Meet the Robinsons, and he also makes a cameo appearance in Wreck-It Ralph. He is a one-eyed octopus who lives without water, and works as the Robinson butler.
When Bud Robinson shows Lewis Robinson around in the future, they come across Lefty, who opens the door. Lewis thinks that he's a monster until Bud clears things up. Bud then asks Lefty where to get to the garage, so Lefty suggests asking Franny Robinson.
Later on, as the Robinsons were having dinner, Lefty unknowingly allows Doris into the house. Soon after, Lefty helps fight Tiny the T-Rex by wrapping his tentacles around the dinosaur.
