Piloswine is called Inomuu in Japanese. Inoshishi means boar, so Piloswine has always been a boar.
Cyndaquil is called "hinoarashi" in Japanese, which is close to "fire porcupine". Porcupine are rodents and thus related to rats. It's categorized as "hinezumi" in Japanese, or "Fire rat". For those that think Cyndaquil is a hedgehog, well in Japanese hedgehogs are called "harinezumi", or needle rats, so it could still qualify. Now if you think Cyndaquil is an echidna, then it's even more interesting as echidnas are called "harimogura", or "needle mole", but also "needle earth dragon". So if you don't think Cyndaquil's a rat, well, maybe it's a dragon.Rat: Cyndaquil?
