The Ochre Jelly, also known as the Ooze in the NES version, is an enemy in the original Final Fantasy. They are weak to Fire and Ice-based spells, so use Blizzara or Fira to mop up a whole group of them, although physical attacks also work well. Do not use Lightning attacks, because the Ochre Jelly will absorb it. It is a rare enemy, only appearing in the third, fourth, or fifth basement of the Cavern of Earth. They appear in groups and are not tough, but they may catch a party off guard if the HP level of their offensive mages is diminished.
