This TF2nimal is not a roleplay species.
This ancient aquatic creature is thought to be the origin of all Spy species. Not much is known about its lifestyle as of now, due to having only just discovered the creature's fossil. Scientists presume it was hunted by the Aquatic Pyro, since both lived during very similar timelines. It is thought to have been able to surface out of the water for a short amount of time, but had to breathe water nonetheless.
A chain link of bones revealed that it had tentacles, thought to be used for trapping prey. It could have also squirted ink like an octopus for escaping from the above mentioned Aquatic Pyro. Its diet mainly consisted of Ammoneers, albeit tough prey.
