As of today, you're old enough to choose your first Breeding Box—the container in which you'll create your offspring! That's where you lay the eggs, the mæølę will fertilize them, and then you'll nurse them until Hatching Day. So pick the box you really vibe with. Perhaps something with more vibrant colors, if you like? I definitely recommend the built-in speakers to play custom music during the ovuliparity process, plus custom handles to grip as you expel the eggs. You only produce 22 broods in your lifetime (prior to your first molt), so you should make the most of it!
