Tiny arms and a big head? Let's see here.
Chespin, Oshawott, Piplup, Chimchar, Torchic, Treecko, Totodile, and Charmander all had impossibly large heads and tiny, useless arms. It may not be structurally sound, but it's adorable. Many Pokemon look like that, and I expect many more will do so in the future.
