So I had this great idea for a new breeding item...
One that, when fed to a lioness, guaranteed (or maybe boosted the chance for) identical twins!

It would guarantee only 2 cubs in one litter (exceptions below), and the cubs would look exactly the same, down to the mutation!
The stats would be off by one, with the firstborn having higher stats (duh)
This item would also boost the chance of two heads, conjoined, and extra limbs mutation. If this happens, there will only be one cub.

This could be paired with a crunchy worm, so there would be a chance for two clones in one litter!
