This is gonna be a sort of challenge I guess
The tribe can only get food from rabbils, crabbits, etc. Only if they are desperate will they eat something from a plant.
This tribe strives to be the strongest, to be able to kill anything in their path with ease.
The weak are not appreciated, sometimes even left to fend for themselves in the wild when they reach a certain age. Though, they might be loved by some nichelings, and if those nichelings are strong, the weak one can stay, though all their food is supplied by themselves and the ones that do love them, and the weak are almost always not allowed to breed.
The leader must always be one of the strongest in the tribe.
