Create a humorous animated short showing a chaotic morning where a man oversleeps, wakes up in panic, rushes through his routine, grabs a quick breakfast, gets ready in a hurry, and runs through a rainy city trying to catch the bus. After arriving at work, he faces a stressful moment with his boss, only to suddenly fall backward and reveal it was all a nightmare. Use expressive characters, fast-paced action, exaggerated emotions, and a playful cartoon style.
