I was just at my local GW and was surprised to find if you buy a carno it can turn into a troglodon, if you buy Kroxigor they turn into warspawned. But I forgot to ask about terradons and ripperdactyls. I was thinking of picking up a primordial starhost. So, yeah, do I get ripperdactyls in it?
The plastic kit that builds Terradons can also build Ripperdactyls. There are alternate parts. The kit was a contemporary of the plastic Carno kit. Double check that the kit offered in the starhost deal is that 8th edition kit.
