Wait how did he get the book in that egg?

Insane troll logic ftw

Ya know...the Cubone has a point though...everything we know about Cubone does state that...well...ya know...

Maybe the Marowak's skull-helmet is now its actual skull, like an exoskeleton (or maybe a turtle shell?).

That might not tidily explain pregnant Cubones, though, or multiple children for either.

Perhaps it's the case that the skull around Cubone's head FORMS into the shape of its mother's internal skull?

Like, through genetic memory or some other handwave shenanigans that will leave whatever bright mind that coined it spinning in their grave like Charles Darwin?

There is a theory that cubone is a baby Kangaskhan and the skull was its mother's, but with eggs nowadays its pretty much discredited at least in terms of gameplay mechanics

If by "theory" you mean that the baby Kangaskhan looks exactly like a helmetless cubone, then yes, it is a theory. Gamefreak clearly discarded the plot early, but never bothered changing the sprite. Sort of like why the truck is there by the SS Anne, or the one-off mention a girl in the Burned Tower that never actually shows up - an intended plot point that fell through.

It's more like the Gen 1 pokemon weren't intended for genders or eggs to start with. (Hence why you have Nidoran boys and girls as separate pokemon types, the only pokemon where gender is a separate species without really having much to differentiate themselves the way that Tauros and Milktank might hypothetically be the same species, and yet are obviously wildly sexually dimorphic.)

Granted, even in later gens, there are breedable pokemon like ghost types that are supposed to be the ghosts of long-dead human Pharaohs that give birth to more entombed human's ghosts.

Wow, I can’t believe I never noticed that before.
