Moogles are from Final Fantasy games. I've gathered a bunch of images of them here. Just click on them to take a look. The most famous moogle is Mog. The pronunciation of Mog, in Japanese (where the character was initially created) is "Mow" as in "Mow the lawn" and Goo as in "Google". However, Americans usually pronounce it as if it rhymed with "fog". Moogles can usually speak human but say "Kupo" a lot. You might have seen other moogle sites with "Kupo" or it's variations written all over the place. "Kupo" is just a sound word that moogles make (the Japanese have about a million sound words...) Enjoy.
