'With the other Primal Pokemon, it has been slim pickings in what we've managed to research about them due to how little they've been found. Meanwhile, here comes Primal Zubat, who utterly plague almost every Cavern throughout the entirety of Tamago, as well as their evolution, Primal Golbat.
Strangely enough, Primal Crobat's evolution is exactly like its non-Jurassic counterpart- it needs friendship in order to evolve. Not that it matters, considering Primal Crobat is still as vicious as many other Primal forms, to the point those who evolve it have even been injured by their own Pokemon.
Remember, everyone… Primal Pokemon aren't the same as regular Pokemon. They're much further into the primal instinct of it all; they're not pets, and frankly, shouldn't be owned by a trainer who can't deal with them. Be careful when training them…'
