Moleville Moles
A hard-working mole is a good mole! The people of Moleville are dependable laborers, and friendly to boot. They're content to work hard in the mine every day to support their way of life. They always watch out for each other, too, and extend the courtesy to visitors as well. Nothing like those uncouth Mega Moles. No, sirree.

Anyway, as far as their role in this game goes, these friendly fellas are pretty much just thematically appropriate Toads. They throw you a little dialogue and help you up into the mine, but that's all they have for ya.
