Fairy Tale: 4 year old

Instruction:

Okay now write this into a story using simple words and sentences, suitable for a 4 year old's reading comprehension level. Emulate the style of a writer like Mo Willems.

Rules:

- Keep the length to under 12 pages of 2-3 sentences per page.
- Don't use metaphors or similes, and don't use onomatopoeia.
- Don’t include references that aren't needed in the story
- Don’t describe the named characters at the very beginning of the story — the reader already knows who they are and what they like
- Start the story with "Once upon a time" to establish that this is fairy tale. The first or second sentence should spark curiosity
