Just a quick suggestion that home island should be filled with bluebirds! Why? Since in the storyline, Adam was taken away from his family by bluebirds, so I suggest that home island would be filled with bluebirds and not just Adam's family since I find it a bit too easy. Considering that home island is a killer mode island, just having Adam's family take berries and meat would be trivial since if you get nimble fingers or cracker jaw into your nichelings it would lead you to be able to collect nuts (which are abundant) while Adam's family can not because of their lack of nimble finger/cracker jaw.
