I imagine it going something like this:
After you defeat Plantera, parts of the underworld become unsettled (specifically under one of the oceans), start erupting, and pushing toward the surface in a similar way that hard-mode biomes spread. As the the Volcanic biome reaches the surface, it would start creating the traditional volcanic cinder cone (or a full up volcano for large world maps), and underworld creatures could start spawning on the surface in this area (possibly with some special biome specific variants). After the Cinder cone is established, the Volcanic Biome would either stop growing, or slow down dramatically.The emergence of a cinder cone on the surface could create new randomized events such as Eruptions, Pyroclastic flows (basically lava pouring down the side of a cinder cone), Lahars (massive mud slides), Acid rain, and periods of volcanic dormancy.
- Some possible new resources: Rhyolite, Potassium, Zinc, Magnesium, Lehua Trees, Coffee Trees, Grape Vines, various mosses, and the glorious Argyroxiphium, or "Silversword" plant. (Maui Plant of the Month: Haleakala Silversword | Maui, Hawaii)
- Possible mobs/critters in such a biome (in addition to the usual Underworld fare) might be: Pacific (or Terrarian) Sleeper Sharks, Lesser Flamingos, Iguanas, Cormorants, Sea Lions, Vampire Ground Finches, Komodo Dragons (not really a volcanic dweller, but would be really cool!), Carnivorous Caterpillars, and so much more! (https://a-z-animals.com/blog/these-7-animal-groups-live-near-volcanoes-heres-why/)
- A possible optional boss for the area could be a Fire Elemental (or maybe a Djinn) who, upon defeat, would put the cinder cone into a state of dormancy. (It could also drop a box of Bran flakes... 'By fiber be purged', along other items.)
Anyway, its just a thought.
