Rory's Story Cubes

I was meeting up with long-time-not-seen friends tonight and these story dice started rolling. We were too tired by then to make a proper use of them, but hopefully we can have another go some other time, as it's an interesting way to spend a geek evening.

Story from the cubes, from left to right: Once upon a time there was a tree and one of its flowers decided to become a comet and learn how to fly away from Earth, so it rolled a D6 and checked what happened in a rule book, whooosh, the flower turned into an alien and didn't waste any more time to fly away.

What's your story from these cubes?
