With the continent being irradiated and a combination of competition and predation putting immense pressures on the last Pissing Sky Bushes of Dingus. While most other populations of Pissing Sky Bush adapted by incorporating more and more lead within their tissues, the slightly lower amounts of Radiation meant the marginal population of Pissing Sky Bush took on a different solution. These would give rise to the Pissbauble, which has become an epiphyte that grows upon the tall flora of Dingus such as Canarpines or Tiertrunk Nolms. With all the evolution of this species, the last remnant populations of Pissing Sky Bush on Dingus would eventually wither out of existence.

The first adaptation was the fact the Pissbauble no longer has a pissballoon stage, instead remaining in their pissbaby stage with the helium sack growing on the top. The root systems of the Pissbauble grow over the tall flora species they live on, allowing them to remain in place while they take in sunlight for photosynthesis. Since there is no soil on the tall flora they grow on, the Pissbauble instead has their roots take in nutrients from the air around them, though this limits this size and has resulted in them having shrunk in size. The helium organ grows in size while remaining attached, becoming bigger and bigger until it eventually bursts, launching spores that then get carried by the wind to land on a different large flora. While the species does have a resistance to radiation, any spores that land on the ground often to not survive on Dingus due to both the shadows produced by towering flora and that the radiation is typically in higher concentrations at around ground level.

By a small chance, some Pissbauble spores got carried by the strong winds of a storm and managed to land on the nearby landmass called Kamm. While their relatively small in number, a population of Pissbaubles has established themselves on the continent's beach. The native Pissing Sky Bushes on Kamm did not die out on the arrival of these colonists, since radiation levels are much lower than on Dingus and as such the two species live alongside one another on Kamm.
