It seems Bugs Bunny is practically invincible. However, there is one character that has duped Bugs before. That character is Cecil Turtle. Although he only appears in three theatrical shorts, he manages to constantly outwit Bugs.
- Cecil first appeared in Tortoise Beats Hare, loosely based of the Aesop's fable, The Tortoise and the Hare.
- Bugs gets very envious and competitive after losing to Cecil in Tortoise Wins by a Hare. Bugs puts on some getup to look like the turtle in the hope of winning the race, but he is foiled due to a bunny mob that tries to rig the race.
- In Rabbit Transit, Bugs has one final race with Cecil. This time, Bugs wins the race; however, Cecil manages to trick Bugs into confessing that he broke the speed limit in a 30 mph zone. Thus, Bugs is thrown in jail while Cecil has the last laugh.
