Because I'm insane and like to have multiple things going on at the same time, collecting every mutation wasn't hard enough for me apparently (Nearly done!) so I'm planning on collecting every special base as well! I'm not fussed whether it's bred or not, just want them in my collection lol. Mutated lions I already have with a special base do NOT count!
I might be on the look out to buy cubs with a special base, so let me know if you have cheap ones to buy :) (I'm currently saving up for lethals, right now!)
