An acrobat is a person skilled at balance and agility stunts, while "batty" is a slang term for "crazy" (as is "Bugs").
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, but soon makes a hasty escape when Nero takes a swipe at him.
Nero manages to get out of his cage, and chases Bugs around the circus grounds. Bugs at one point ducks into a dressing room, coming out as a clown trying to convince Nero to laugh, which he eventually does — until Bugs takes some whacks at the lion with a wooden board. The lion then chases Bugs into the big top, where they swing around acrobat swings. Eventually, Bugs tricks Nero into a cannon and sets the cannon off, causing Nero to do a hula in his 'skirt', plays the ukulele.
