Here's something me and TwoMario bantered about for a minute or two. Since I'm a nerd for itching torture, why not make one of my own. XD

Desperate but Lethargic

The orange Lignum is a mutated strain appearing only as a rare anomaly, as the result of diseased Lignum cross-pollenation and/or excessive floral inbreeding. The orange Lignum is perpetually malnourished and does not feed as often as it should, and even when it does, it's feeding process is slow and strenuous. It lacks the usual tickling instincts of most Lignum, instead extracting fluids via lazily letting their victims thrash around in their goo. Their goo is a mutagen of the purple Lignum's sensitivity enhancer that instead induces a fierce and mind-shattering itching sensation. The orange is lethargic and doesn't do much apart from hold the victim in place, letting them thrash around a decent bit in the particularly warm goop. They feed almost exclusively on sweat, other fluids being an exceptionally rare treat for them.
These Lignum are exceptionally rare due to being a malformed variant of purples and reds, and they don't always live too long because of their less aggressive natures. Because of their docility toward anything but extra curious passerby, they're sometimes kept as exotic plant-pets by some particularly eclectic dommes and sadists.
