'Undead coral octopus
The coral octopus has symbiotic relationships with unique corals of its choosing. They will grow in to armor to protect it while becoming one with it completely. The coral will then excrete poisons that come from what the coral octopus consumes.
The coral octopus is still perfectly balanced with the coral that had now taken a deeper root in its body after it died. With the undead darkness mana and energy within its body, the coral had mutated and grown too. It is tough enough to defend the coral octopus while still consuming whatever it eats. This is an extremely unique undead monster.'
Walker cursed internally seeing that he was facing a tougher undead. The coral octopus would have been weaker if it wasn't an undead. The reason it was so hard to beat now was because the coral that it had been balanced with was now taking over. With the undead ghost ship captain in control, it was now a force to be reckoned with.
