I imagine, as many others do, the creeper being very plant-like. I decided to go with the approach of it being a parasite latched onto another creature, namely a pig (real ones know why).

The parasite, of my own making, is the Hisser. It resembles a plant, pigs are the most drawn to it by sight and smell. The hisser, once a pig is close enough, latches into it and begins its conversion. Any being it does not want to use will be met with intense cat-like hissing.

The alternate path of the hisser is to be hunted and eaten by ocelots or stray cats. The hissers own hissing will not work on felines. The ancestral trauma of these interactions has caused all hissers, and thusly creepers, to fear cats.

Creepers have boom sacks, filled with sulfur, which causes the creeper to explode. The reason for exploding seems to be an extreme unfamiliarity towards Players, or perhaps an epigenetic response of an ancestral trauma, or to spread its kin! No one of the world truly knows.

The Saunter, a nether variant of the creeper, is a larger and more ranged mob. It takes over hoglins and has integrated with the natural fungus of the dimension! It spits fire and, if necessary, will use melee attacks (mostly ramming).

The Lunger is the rare result of an Enderman improperly preparing and eating a Warped Hisser (same as a regular Hisser, but blends in with warped fungus). Two alien creatures joined, one overtaking the other, birthing a beast straight from hell.

The Hisser only knows how to maneuver a quadruped. So when in the body of an Enderman, it will twist the body to crawl on all fours as it sprouts from the spine. It grows and blooms, adopting warped fungus into itself.

The Lunger is a grotesque creature, sporting multiple faces and keeping an enderman’s eye functional. It can charge at a target faster than most other monsters. It can stalk, it can hunt, it will locate prey without fail. This abomination will utilize its host teleportation in order to sneak up on its targets.
