Is Flurrie from Paper Mario: The Thousand Year Door of the species known as Ty-Foo?

Solution 1:

There is no official information either way, and all we have for clues are two bits (from here) that somewhat contradict each other:

• Punio says the Puni Elder calls Flurrie a "wind spirit", which is indistinct but does imply something less than a cloud.
• Flurrie's Japanese name is Clouda (クラウダ), and some (but not all) other languages use cloud-derived names.

MarioWiki currently does not place Flurrie in the "clouds" category, so it appears the prevailing opinion amongst its editors is that she's not a cloud, and therefore not a Ty-Foo (or a Foo). But again, there's nothing definitive for either claim.
