Tyrant Jelly

This silvery ooze contains the preserved larva of a giant insect, almost like a monstrous brain.
When an ooze infiltrates a colony of giant bees or wasps and consumes a queen egg, a strange reaction sometimes occurs between the ooze's fluids and the egg, resulting in a tyrant jelly—an intelligent ooze using an immature insect as a primitive brain. The tyrant jelly has unusual powers over vermin, and quickly takes control of the colony, sending its drones to gather food to sate its unnatural hunger. Other vermin are attracted to the scent of these creatures, and then fall under the tyrant’s sway—a colony often has giant bees, centipedes, spiders, and wasps working together.
A tyrant jelly’s primary interests are food and survival. Magic or telepathy might allow a creature to bargain with it, exchanging food for its cooperation. Some insect cults hunt tyrant jellies, believing their strange substance has properties similar to a giant bee’s royal jelly or can increase the intelligence of other vermin.
