An underwater tank who is immune to jellyfish stings AND acts as a giant scuba tank for its riders. Oh, and it passively produces the equivalent to mutton for herbivores. Facing something you'd rather avoid in the water? Just take your turtle onto the land; that's right, despite not having an O2 stat, this mount can also travel on land. For how easy it is to tame, this thing offers incredible value to any tribe that has one.
