Ok, those depths confuse me a lot...I mean, the grassland is exactly the same...
The point of this topic is to ask the TRUE differences between Aurora Isles and Jigsaw Valley, because some monsters have wrong locations in there that need to be changed.
Jigsaw Valley = Gremlins and Constructs?
Aurora Isles = Jellies and Wolvers?
Greetings
Your summary is good, except that the Low Gardens are mostly beast and construct. I can't picture any slimes in there, actually.
