Acrobatty Bunny (1946)

A circus is being set up just above Bugs' rabbit hole, causing much noise and vibration. The Lion cage is set up directly above the hole, and the Lion takes deep sniffs (alternatively yanking Bugs towards the hole or throwing him back) to determine that the animal below is Bugs. When the Lion (whom Bugs eventually refers to as "Nero") roars again, Bugs comes to the surface to see what's going on, riding an elevator that makes twists and turns. Bugs tries to reason with the lion ("I'm the tenant downstairs, and there's entirely too much noise!"), but soon makes a hasty escape when Nero takes a swipe at him.
