I've cast and painted my alien animals, so here they are, a flock of Feltz. :)
Adult females weigh up to 2 Tonnes and a flock usually has between 3 and 8 females.
When threatened by predators Feltz defend themselves in 2 ways. Faced with large predators they sit down, leaving only their armoured back and skull exposed to attack. Against smaller predators they also sit down, but on top of the predator.
Feltz taste of chicken.
