Due to the awful quality of that commercial, I refuse to believe that it is from SE. And Seriously, if you're gonna make a moogle, use a cat or a teddy bear. And there was a Nu Mou. Why? And why didn't they put shiny tin foil on a lizard to make a Bangaa?
I can't put my finger on it, but something about Mewt seemed a little disturbing. And I always thought Marche was pronounced "March." And I always stressed the second syllable in Ivalice (i VAL iss). It may be one of the best awful things I've ever seen.

And I do speak a little (not much but some) japanese and I still havce no clue what happened. But it's a Japanese cmmercial, so what do you expect?
