Shapoklyak, an elderly antagonist, blends mischief with a distinctly retro flair, sporting a spring-loaded chapeau claque and a purse housing her loyal rat companion, Lariska. Her name, playfully borrowed from the French term for her collapsible hat, mirrors her whimsical yet disruptive nature. Guided by the motto "One won’t ever get famous for good deeds," she pursues notoriety through pranks, believing mischief leaves a sharper mark than virtue.

Though cast as a troublemaker, her backstory hints at complexity: a lack of formal education later leads her to attend school alongside Cheburashka, revealing glimpses of vulnerability beneath her scheming. Her antics oscillate between harmless chaos—swapping road signs—and elaborate disruptions targeting urban life, often orchestrated with Lariska’s help. She proudly embraces her self-fashioned title of "Card-Carrying Villain," yet her menace stays playful, devoid of true malice.

Her character evolves through fleeting alliances with protagonists, aiding them in resolving conflicts before inevitably returning to her prankster roots. Visually, she embodies a "Lean and Mean" silhouette, her anachronistic 1930s-inspired wardrobe underscoring her timeless eccentricity. Across adaptations, she remains a catalyst for chaos, testing the problem-solving bonds between Cheburashka and Gena the Crocodile. Her affectionate bond with Lariska adds depth, contrasting her solitary mischief with a touch of companionship.
