I think it would be a really interesting addition to be able to create butterfly gardens. It would help with education about pollinators and their importance and could be a unique sort of enclosure to the game. I feel it would be easy to implement them by having them exist in an exhibit that is open air and cutsomizable by the player so they could create large butterfly gardens for guests to walk through by placing the exhibits next to each other and adding foliage to blend them together. Im sure there are other ways to implement them, but thats just what came to my mind. It seems like it would be a really fun addition to me and I hope something similar is added eventually!
