Add Corpse flowers to the Soul Sand Valley

There are a few different species of plants referred to as corpse flowers, but what they all have in common is that they are big and stinky. They could provide that much more hazard to the player by forcing the player to hold their breath when around these large full block sized flowers. This area of effect is just as easy to program as the beacon or conduit.

They have a not so rare chance to generate on top of Soul Soil. When the player destroys one (quickest with an axe) it drops a large amount of Rotten Flesh. But at least now you can breathe easier.
