I'm so happy to see that people can stop being upset over Let's Go and saying it killed the series now.
Well since we have 5 and a half hours to go and I'll still be in a meeting by then, here's my predictions:
Fire: A rabbit with huge burning feet and the ears of a cat
Water: a 6-pack of Coors
Grass: kale
Not sure, I think it might be Fire/Fairy
