It appears in two variants, that can be seen on the right. These are:
left, Ploomweed Dash which appears in the Entry room and the north side of the Prime Eggs Room. They are needed at grade 1, grade 5 and grade 6.
right, Ploomweed Zuc which appear in the Cattle Room and the south side of the Prime Eggs Room. They are needed at grade 2, grade 3 and grade 4.
This creature has been first described by Matis botanist Lirni Gillo (see below an excerpt from the Incomplete Atysian botanical atlas by Komi the Nameless).
“An interesting variety of phosphorous feather-plants that dwells underground, plumash can live up to ten years and is flowering all year round. The plant has large green flowers with five petals. The feather-like central part of the flower with a thick pistil and a multitude of hair-thin staminae emit a bright cyanide-white glow that attracts smaller representatives of underground fauna which then help pollenate the plants. The younger versions of plumash are known as Ploomweed Dash and Ploomweed Zuc.”
Fields of ploomweeds look like eerie white floating fires from a distance.
