Not so fun facts
The problem with two different species reproducing is that:
1.) Sperm can't fertilize egg
2.) Egg could get fertilized but offspring won't survive to adulthood
3.) Offspring that did survive to adulthood is infertile
4.) Offspring could be fertile but offspring's offsprings may not be and they probably carry sucky genes. Aside from being possibly infertile and having sucky genes, it just gets worse after every generation.
So, Marcille is most likely infertile but there's a small chance that she isn't. In the case that she is fertile, her kids would probably have problems.
