Grey Mouse
From MHWiki
"Slightly feistier than their white cousins, the grey mouse is also a very common mouse. They pose very little challenge, and thus garner little reward. Great for the starting mouse hunter."
The Grey Mouse is one of the most common breeds of mice found across Gnawnia. They are worth at least 125 Gold and no more than 90 Points.
