Louie the Lilac

Louie the Lilac has cornered the flower market in Gotham City, hoping to gain control over the entire "flower generation." He kidnaps the organizer of their planned flower-in, Princess Primrose, and brainwashes her with his Stupefying Aromatic Spray. Batman and Robin follow a clue to the villain's lair only to be captured by Louie and fed to his giant man-eating lilacs. With the Caped Crusaders out of the way, Louie heads back to the flower-in to continue his evil plan. Alfred, meanwhile, has been alerted to Batman and Robin's situation, and goes looking for Batgirl to aid in the fight.
