I love Chatot.
To me, it's a very clever design in terms of typing. It's Normal/Flying, and that is a niche that Chatot fills very well, due to being generic and being a bird. Other Normal types derive their secondary typing from the species they're based off of. Pidgeot is a Flying type because it's a bird. Staraptor is a Flying type because it's a bird. And this, again, is a niche that Chatot fills very well due to being a bird. The connection is natural, organic and the result of Game Freak knowing what they're doing with their Pokémon designs.
