The Musky Ox is just a normal Beast with discoloration issues or it has had a less covering paint job in the factory.
There are NO Series 3 BDC in existence, the BDC line only covers the first series of Battle Beasts (#1-28).
ALL BDC were exclusive to Spanish Production BUT not all Beasts coming from Spain are BDC...
There are normal BB found in MOC BDC packages so there´s a connection that´s not completely clear yet and it also makes it harder to find the genuine BDC.
As far as the Carp goes the normal BDC Carp has Pink eyes just like the regular/normal BB version but amongst the BDC some Carps with Yellow eyes have been found and these are considered a ¨variant¨ or at least a rarity.
