Muy Muy is a municipality in the Matagalpa department of Nicaragua.

Although "Muy Muy" means "very very" in Spanish, the municipality was named so by the Nahuatl, for whom "muymuy" means "nutria," which were once found in abundance in the region.

This needs to be clarified, since the meaning of "nutria" is not clear. It seems that in North America, "nutria" means "coypu" (myocastor coypus), an animal related to the beaver (genus castoridae). If this article was written by North-Americans, it probably refers to this animal. However, Nicaragua is a Spanish-speaking country, and Spanish-to-English dictionaries translate the Spanish word "nutria" as "Otter" (genus lutra). To make matters worse, there is some evidence that Muymuy refers to a sand crab or some sort of sand-dwelling animal (emerita analoga) (see the discussion section in http://www.proz.com/kudoz/4345789)
