Bush Max Level Achievement Reward

The difficulty to reach the max level for the Bush is on the easier side, but I kept postponing making the highest level wonder because I was prioritizing other events. Then today, while clicking on something else, I accidentally merged the bushes due to a glitch and ended up making the wonder lol. Anyway, the rewards for the Bush wonder are 3-4 Mystery Tanzaite Eggs, 1 Egg Nest, and 4-5 Gem-locked Egg Chests. I've made two wonders, and each gave 1 Egg Nest. If you get 3 eggs, you get 4 Egg Chests, and if you get 4 eggs, you get 5 Egg Chests. It takes up 4 slots and cannot be harvested. So, I don't think there's a need to make it with bubbles, and since the difficulty to make the wonder is low, I sold it. I guess I'll just make the Bush wonder when I need Mystery Eggs haha
