Lenphester Parasite

Lenphester parasites (len-FEST-urr) are creatures that cause negative effects when caught. They are most notorious for spreading through mobs that Players tend to kill the most, including creepers.

Tactics/Effects
Lenphester parasites only start appearing when the Player has obtained at least one set of diamond armor, or a tier of armor above it. Once the crafting of a set of this kind of armor has occured, the spawning of Lenphester parasites will be triggered.

Creepers are the most infamous carriers of the parasite, including about 60% of the total amount of variations. Most other-dimension creepers cannot be infected, but Overworld variations can. The way to tell if a creeper is infected is if its detonation timer is delayed (usually between 2-3.5 seconds rather than 1.5) and it moves slower than usual. Mobs including skeletons cannot be infected - they have no flesh for the parasites to dig into.

If the Player catches it, he/she will move, attack, and shoot slower than normal. His/her regeneration rate will also decrease. Aside from this, the parasite does nothing incredibly harmful and is mostly just a nuisance, as it can take whole Minecraft days to go away. However, in extreme situations, Lenphester parasites may cause doom if the Player is cornered by hostile mobs, for they cannot attack or get away quickly enough.

To cure a Lenphester infestation (or "lenphestation"), the Player must drink several buckets of milk. The parasites will go away in a few minutes. Some people make the mistake of only drinking one milk bucket, which will not cure the infestation.

Habitat
Lenphester parasites have no specifc spawn place. They only occur naturally in the Overworld, though the only biome they cannot spawn in is the volcano biome.
