Limon smoolks are found in the Agbees Formation, a patch of land in the Mason Barren Wasteland northwest of the Mason Reef. The area is characterized by its richness in limonite and galena. (It is called the "Agbees Formation" after a particular interesting rock there. The rock resembles a terrified face whose mouth is stuffed with bees, hence: "Aaaagh! Bees!" Most of the rocks there do not resemble screaming faces.)
Limon smoolks are unique among smoolks for their sexual reproduction. Should their resilient, strangely strandlike airborne spores land on the pores of another limon smoolk, mild acids produced by the recipient weaken the protective membrane of the spores. The spores then fuse with the recipient's own spores, and the recipient smoolk "wraps" the fused spore in another protective membrane before emitting it into the wind. For this reason, limon smoolks' genomes are larger than their ancestor's, and can even be twice as large. The sexual reproduction might explain the variety of limon smoolk colors. While limon smoolks' color depends on the exact components of their diet and health, individuals possess tendencies towards certain color ranges, regardless of conditions.
Limon smoolks have six consistent color habits. The colloquial names for these habits are: "corn tortilla", "flour tortilla", "gumdrop", "chocolate", "banana" and "lemon." Though two of the color habits are named after tortillas, this should not be interpreted as evidence for the two being especially related.
Limon smoolks have raised surfaces surrounding the pores. Seen from above, these raised surfaces resemble donuts, with the pore being the donut's hole. The raised surfaces are a barrier to wind-blown grit falling into the pore and clogging it. The spores, being lighter, can land into the pore with no trouble. (provided they have the good luck to land there to begin with.)
