I need to write a short story for an assignment and I need some crazy, creative ideas. Anyone have any?

I need to write a short story for school and I’m stuck. I have no idea what to write about and I’d love some ideas.

My story needs to have,

- There must be a quest
– The hero must have an adventure in the process of completing the quest
– There must be a message or lesson learned
– And there has to be a happy ending

I’m not asking anyone to do my assignment for me, I’m just looking for some creative ideas. Ahh i dont know what to do. I’d love some help! Thanks
