I would love to see something like the Bulbo Tree return which was always my goated solution to both water and food management. Easy to plant inside and solve all of your problems but also easy to miss if you didn’t think to cut a sample while on the islands. It was super cool to discover on subsequent playthroughs that something in plain sight was the ultimate nutrition machine.
