Sunny was no ordinary planet. She was round and soft, covered in bright colors, silly shapes, and every letter of the alphabet - from the A near her north pole to the Z tucked near her equator. But what made her truly special, more than her colors or her letters or her perfect roundness, was this: Sunny loved to teach.

One morning, she put on her learning hat - which looked suspiciously like a stack of three storybooks balanced perfectly on top of each other - tucked a pencil almost as tall as herself under her arm, and twirled her way down to her very first classroom.

The room was full of little animals. Benny the Bunny sat in the front, ears twitching. Lila the Lizard leaned against the wall, her tail curling with curiosity. Timmy the Turtle sat very slowly and very thoughtfully at his desk, which is how Timmy did most things.

They all looked up at once.

Timmy slowly raised a flipper. He considered his question very carefully, the way turtles do when they want to make sure the question is worth the time it takes to ask it.

Together, the four of them danced from A to Z - hopping from one letter to the next as Sunny called out the most delightful facts she knew.

The animals giggled and jumped with joy. When it was time for shapes, Sunny tapped each one with her giant pencil - tap tap tap - and named every single one with great ceremony.

That afternoon, Sunny read stories, helped the animals count shapes, and made up a rhyme about moons and hearts that was so silly nobody could finish it without laughing.

By the end of the day, the classroom felt warmer, brighter, and at least three questions smarter.

Sunny gave a gentle spin. The alphabet on her surface caught the light. The shapes glimmered. The letters seemed to glow a little brighter, as if they agreed with what she was about to say.

The three friends cheered. Even Timmy - slowly, but with great enthusiasm.

And from that day on, Sunny the Planet Teacher became the heart of their classroom, always ready with a book in one hand, a pencil in the other, and a smile as wide as the universe itself.
