Jideorays are a parasitic orange slime common in the warmer oceans that attaches itself to creatures to feed directly on their skin. Small fish will sometimes allow members of their school to host jideorays, as the toxic pheremone they produce also wards off most predators. Jideorays have a hard time keeping their host alive for long periods of time, but extend their lifespan somewhat by completely covering their eaten flesh with a bright orange jelly.

In rare cases, some animals may find themselves completely enveloped by this orange slime while still alive. At this point the jideoray will often assume complete muscular control over the creature for the rest of its life.
