In this animated misadventure, Bugs Bunny and Elmer Fudd find themselves in a cluttered laboratory where a mad scientist is zealously chasing a “Jekyll and Hyde” potion. Elmer’s endless attempts to brew the perfect formula keep crashing in comic fashion, sending a test dog darting out to graze on the grass outside. After a string of spectacular failures, Elmer traps a rabbit as his next subject, and Bugs Bunny becomes the unwilling test subject of his latest scheme. When Elmer administers the potion to Bugs, the initial effects seem elusively mild, leaving the scientist frustrated and unsure of his success.
In a twist of mischief, Bugs responds with a counter-move: he hands Elmer one of the potions, giving Elmer the same early side effects that the other animals endured. The laboratory fills with panicked laughter and a flurry of wild reactions as Elmer and Bugs navigate the strange new sensations together, each trying to outthink the other in a delicate dance of wits and wiggles.
Then a bear lumbers into the lab from the nearby forest, and confusion erupts. Both Bugs and Elmer mistake the bear in a hilarious scramble of recognition, until Elmer’s temper erupts at the “bear,” whom he still believes is Bugs about to thwart his plans. The real Bugs peeks in from the window, revealing the mix-up just as the bear’s presence becomes undeniable.
Realizing the mistake, Elmer finds himself suddenly hunted by the bear, who chases him around the lab in a chaotic chase scene that blends slapstick with frantic dodges. Desperate, Elmer pretends to be dead to fool the larger predator, and his ruse is aided by a notably foul odor that oddly saves him from the bear’s claws. Just when he thinks he’s in the clear, he fears the bear’s return—only to discover that it’s Bugs again, masquerading as a bear to fool their shared audience.
Throughout this caper, the bear stands off to the side, a bemused observer of the chaos, while flashing a curious set of rebus picture cards to the audience. The cards show items like a screw with a ball, a cracked pot, a dripping faucet, and bats in the belfry, turning the scene into a playful, meta moment that invites viewers to puzzle along with the characters. The tension between misidentification, magical misfires, and farcical escapes unfolds with a steady rhythm of sight gags, quick banter, and the timeless comic chemistry between Bugs Bunny and the relentless, well-meaning Elmer Fudd.
