Petrichor

Petrichor is the earthy scent produced when rain falls on dry soil. The word is constructed from Greek (πέτρα) petra, meaning "stone", and (ἰχώρ) īchōr, the fluid that flows in the veins of the gods in Greek mythology.

Welcome to the lush world of Petrichor; you are a cloud. Your entire purpose in life is to expand, sire other clouds and water crops. Unfortunately, your mates (who are also clouds) have a similar plan. It’s up to you to manipulate the weather and assimilate these rogue clouds to contribute to the growth of as many crops as possible - all in order to claim the title of Most Valuable Cloud.
