Unlike the pre-existing conjoined cubs, this varient is a single cub with the attributes of another.
Teeth, limbs and other body parts can be seen sprouting from vital areas of the cub. this certain variant dies at two months, as due to having its insides messed up by the cub it absorbed.

messages:
one month:
What? only *number of cubs*?? you where sure there where more! did the bat lie? apparently not, as their mother informs you that the missing one had been absorbed in the womb, causing the deformation of another. she's worried it won't survive.

two months:
*cub name* had died last night due to organ deformation.


Note: you still get the same number of cubs predicted in your litter.
