Max Level Grass Wonder Reward

I worked hard collecting the grass that spits out water, and made a max level Grass Wonder. The reward is 14 Blade Dragon Eggs, and a few stones and treasure chests. It takes up 4 slots total. When you harvest it, you get mossy stones, not high-level ones. I'm keeping it in my bubble for now. The upcoming racing event will likely feature stones and hills, so I'll use it then.
