The Poisonous Oozlebachr is a species of Oozlebachr that has a modified jet that spews out poison at the back of the creature, poisoning all other cells attempting to harm or eat it. The Poisonous Oozlebachr was made during a genetic mutation when the Oozlebachr planet was blown up, and some Oozlebachr were carried to another planet. The mutation seems to be more effective than the spike on the tip of the Poisonous Oozlebachr. Its filter mouth was separated into two individual mouths during the mutation.
- The Poisonous Oozlebachr was originally green, but then turned to purple after devouring a strange purple plant that washed into the tide pool.
