I'm mad how long I knew it was about water, cold air, and weather without figuring it out.
I feel the pain. I got "Animal Life/Plant Life" and "Grow", as well as a few seas and I was sure this was about some animal or sea life or something..... I didn't get Cold until 106 though, which started putting everything together. Ice and Cold were really key and it took me far too long to find those two words.
