Soul Forest Dimension. There are a lot of vines all over the place and once you stay there long enough the place will look really epic. You can occasionally find Baneberry, Blueberry, Blackberry, Cranberry, Raspberry, Razzberry & Strawberry vines in there.
Also there are lots of grape-trees around here.
The Soul Forest Biome currently holds one mob the Blue Slime (name not yet permanent).
