The doublestalk replaced its ancestor the orange spore stalk in Yokto rocky. It is almost identical to its ancestor except it has 2 spore chambers. Their spores which are still spread by the wind and are still kept inside a chamber placed on top of its stalk which is opened once the chamber is filled with spores. The spores can form thick orange clouds able to choke small animals like its ancestor before it, only, the doublestalk is even extremely numerous and the spores can choke bigger animals. The reason for having 2 is because there are not many viable spots o in the rocky region to take root so they double their chances of success by making even more spores.
Their roots drink water preventing it from drying out and also to cool down the cell`s in its body, the water will leave the doublestalk through the stem, making it moist to the touch and photosynthesis more efficient. It also has a special adaptation it can stay dormant in the winter when it snows. Thus it will only spread its spores in the spring when the snow has melted and the soil is moist.
