I would love to see a Lapras baby but I get the feeling it would look a lot like a Shellos. :P
I've long held the belief that this world is in desperate need of a Tropius baby. I can understand why Game Freak is holding out on us though. We wouldn't want to risk going blind from the adorableness.
yes, I totally agree, Tauros baby, Miltank baby... maybe even a Farfetch'd baby or a Stanler baby (which would make sense, as Reindeer only get their Horns at "puberty")
although, it would be funny to have a doduo baby, like, with one head...
