The little doduo baby looks like it's about to kill one of it's heads....
Maybe that's the evolution method? One of the heads is killed so the other two get the nourishment they need in order to evolve. Explains why Doduo only has two heads!
Grimey has a nose
I suspect the Girafarig pre-evo (called "Twinz" by the translators) is supposed to represent a yin-yang symbol (like Girafarig) and a conjoined fetus. If I had to tweak the design to make this clearer, I would add a sphere of gelatin like Reuniclus to represent a womb.
I love them all!
As cute as they are, I kinda am glad they didn't go into the final games. That left much more space for other cool Pokémon to go in. That Meowsy has to be the cutest thing ever though. Can't go wrong with a kitten ever.
