T_T the data mine showed walking cycles. I theorized it was supposed to be put in the game, but they either didn't have enough time, or, like you suggested, not enough space. newer games usually solve space problems, though. so I'm hoping USUM will include it.
omg, you know what would be AWESOME as a gen 2 alolan form? an alolan form mantine and mantyke, with like, Polynesian markings and maybe some different colors? and it could be water/ghost! or maybe I just watch Moana too much XD
ooh, you know what? an ice type houndoom would be awesome too! think about it, it would have like, horns made of ice, and have like, long fur, matted with ice and snow.
