Nimbi

From the Super Mario Wiki

Luvbi, a female Nimbi created from a Pure Heart.

Yebbi, the yellow Nimbi sage.

Nimbis are the cloudlike citizens of The Overthere in Super Paper Mario. They speak in pseudo-Elizabethan English and look mostly identical to each other, save for a difference between male and female (the females have hairstyles.) Among them are four sages: Blubbi, Yebbi, Rebbi, and Whibbi. Each one has a unique mustache, and the colors of their robes correspond to their names (e.g Blubi-blue, Rebbi-red, etc.)

Many Nimbis' names resemble days, seasons, or months.
