It's suggested that the name comes from Frog and Croak. While this is possible, it would be strange for it to not reference water in some way. Another possible pair of words for it to come from is Frog and Soak. The "ie" could be just a diminutive, of course. Aielyn (talk) 00:25, 9 January 2013 (UTC)
Considering that the French name is partially derived from "mousse" and it would be odd to have a double animal name derivation rather than say an animal name and a water reference, I'll bet it really is "froth" + "croak" too --Joec (talk) 20:42, 9 January 2013 (UTC)
Froakie's Possible Origins
Just posting this in the discussion in case people may have problems with this: Froakie's inspiration seems to be based upon a few factors, most notably its foam pouch is based upon various species of frogs whom create foam nests for their eggs to keep safe in. These foam nests are formed from the frog's behinds and, while creating them, eventually envelop the backs of the parent frogs, hence the backpack resemblance Froakie's foam pack has and why it is located upon its back. This seems to also match up with Froakie's japanese name, as it contains matsu which translates to bubble or foam. Here's an example image of a frog and its foam nest. Unfortunately, I am not quite sure which exact species of foam nest making frogs Froakie may have been based on.
Now then, onto the origin of the white round dots upon its face. These dots, coupled with the foam pouch and white glove-like markings it has seems to indicate that Froakie's possible origin is that of the image of Japanese folklore thieves and robbers, an example drawing of said thief/robber design can be seen here. The foam backpack of sorts upon Froakie resembles that of the thief's furoshiki, a japanese cloth bag seen on the image of said thief that they carry their loot in. The dots resemble the ends of another furoshiki tied upon the thief's nose, used as a mask of sorts to hide the thief's/robber's identities. The gloves are also simply a sort of thief/robber general stereotype as well. This seems to indicate that Froakie may posisbly end up as a dark type upon evoluton; this guessing of type, however, is just pure speculation on my part. - 050294 (talk) 00:23, 10 January 2013 (UTC)
