Cartoon Planet Riding a Sparkling Comet

Cartoon-style space scene: a cheerful, googly-eyed planet riding on a bright, icy comet streaking through a starry sky. The planet has a big smile, tiny arms waving, and a cute round belly. The comet glows cyan-blue with a long magenta-pink tail of sparkling ice, leaving a rainbow trail. Use bold black outlines, flat cel-shaded colors, and simplified shapes to evoke classic kids' cartoons. Background features deep purple space, twinkling stars, a distant ringed planet, and soft pastel nebulas. Lighting from the left creates glossy highlights on both planet and comet. Dynamic diagonal composition, with the comet arcing from bottom-left to top-right. Optional playful touches: a tiny satellite waving, dust particles, and a small “Hi!” flag on the planet to boost whimsy.
