>>45428568It's weird how they decide the typing in some Pokémon, but it's not just a thing of this gen. Spiritomb could have been Ghost/Rock too, and Probopass could have been Rock/Electric (and this case is weird because after this they made Alolan Golem which is just a Probopass ripoff with the typing it should have been).
It's also funny how they decided to make the new birds pure Flying, proving the other birds didn't have the need to be Normal/Flying.
