One night a little robot landed in a forest. He was sent by aliens to investigate the environment. The robot had abilities to see heat waves and transform into anything or any item.
The aliens had a control panel to steer the robot and they headed for a tree. The tree had a horse chestnut on it so the robot went there and transformed into a horse chestnut.
When it was Autumn and all the nuts were falling off the trees the horse chestnut was shaking. Suddenly it fell and hit the robot by accident. The robot fell and it was damaged.
