About this Mod

Rain Rot is what could be considered a Rain World 'furniture' mod, although it includes more than just decorations — some of the additions are also functional!

Rain Rot (as of writing) adds slugcat plushies, iterator plushies, paintings for each karma mural, and a handful of other things like tunnels and Pebbsi. Check out the gallery tab for a more detailed list of what's included.

In the future the mod may be expanded with more Rain-World-themed items and blocks (such as lizard plushies), however Rain Rot will never include custom mobs, world generation, or other major features — in other words, the mod will always primarily be a decoration mod, with only minor functionality on the blocks.
