Realistically a rajang has no protection against lava. All it is covered in is simply fur, it has no special protective plating or armour for it to move through lava like it does in the game. Heck melynx walk and jump around lava as well and like rajang only have fur covering them. The walking/moving through lava is pretty much a game mechanic.
