Got the rewards after maxing out Water, lol

Because of the Mushroom Rush event, I popped the 'Misty Mountain' I had stored in a bubble. I farmed dragons to make lots of clouds, and then I sprinkled cloud rain everywhere to create ponds, merging them when they turned into mushrooms.. After reaching 1st place in the Rush event, before re-bubbling the 'Misty Mountain', I wanted to recycle it, so I worked hard making ponds and merged them together. So I reached the max level. I was slightly expecting something good because the rewards for maxing out the Living Stone before were great, lol. It gave me a bunch of XP, 3 Level 2 chests, and a Level 7 pond. The bottle is pretty in its own way, but I can't farm from it and it takes up 4 spaces. I'll probably just bubble it again lol. That's probably why they left me with the Level 7 pond. To collect Stone-generating pools with it, haha. The Stone is already maxed out.. I guess I'll just use it to level up the Stone-generating pools and the occasional Golden Midas Tree.
