I think there should be more animals which could be tamed. Right now along the river there is plenty of shaleback but in the jungle there is no such variety of pets as somewhere else. I think it would be good if gorillas and reptile rhinos could be tamed because the are just panthers and crocodiles and it is pretty much all, whereas other biomes have all kinds of animals.
(Yeah I know I can buy eggs for spiders, shoebills and sand reapers but they cant be tamed as other animals so I dont take these buyable animals into account)
