Use the attached comic as visual and narrative reference. Create a 12–15 second animation styled as a wholesome children’s picture book: pastel colors, pale blue sky, green hills, minimalist characters, gentle animation. The hero is a tiny round light-purple hippo. His best friend is a miniature toy steam locomotive. Opening: Everything is extremely sweet and innocent. The hippo and locomotive happily travel and play across green hills. Soft cheerful children’s music. A small black crow suddenly flies down, grabs the locomotive and carries it away. The hippo sadly watches them disappear. Journey: The next day the hippo bravely sets out to rescue his friend. Quick heroic montage: he climbs a hill, crosses a valley and reaches a large oak tree. The crow sits on a branch beside the stolen locomotive. Sudden comedic shift: Without changing his cute, calm expression, the hippo suddenly becomes astonishingly determined. A ridiculously fast classic-cartoon slapstick sequence begins. A spinning cartoon dust cloud covers the action. The tree shakes wildly, black feathers fly everywhere. The surprised crow briefly pops out, gets pulled back inside, then shoots from the cloud like a cartoon rocket and disappears over the horizon. Use exaggerated cartoon sounds: boings, pops, whistles, rattling branches and a distant “poof.” Keep everything surreal, playful and unrealistic. The hippo remains adorable and calm—never angry, scary, muscular or threatening. Immediately afterward, everything becomes peaceful and the gentle music returns. Final shot: The hippo calmly stands beside his rescued locomotive as if nothing happened. Slowly zoom into his innocent, expressionless face. A warm Russian children’s-story narrator says: «Потому что никто не смеет так шутить с маленьким бегемотиком.» Pause. Extreme close-up. «Никто.» Key direction: The first 75% must genuinely feel like a sincere wholesome children’s cartoon with no foreshadowing. The viewer expects courage, friendship and kindness. The joke is the abrupt one-second burst of absurd cartoon chaos followed immediately by complete storybook serenity.
