Gibberslugs. A creature afflicted with gibberslugs has one round in which fire can be applied to the place where the slug burrowed, killing the slug. If the slug is not removed, the creature takes 2 (1d4) damage at the end of its turn each round until it is reduced 0 hit points at which point the slug reaches its brain. A lesser restoration spell kills a gibberslug, as does eating a darkscape mushroom. A creature reduced to 0 hit points by a gibberslug drops into a nightmarish coma for 1d20 + 4 hours during which it undergoes a horrific transformation into a gibberling . It can only be awakened from its catatonic state with remove curse or greater restoration , at which point the creature is dying.

Darkscape Mushrooms
Darkscape mushrooms are marbled grey mushrooms. They are nature’s response to an incursion from the outer planes, and a character proficient in Arcana, Nature, or herbalism kit can identify them and their nature (no check required). Darkscape mushrooms can be consumed to cure a creature of gibberslug infestation, and also act as deadly poison if ingested by gibberlings, inflicting 26 (4d10 + 4) poison damage.
