Meditation Room
From MHWiki
"The second floor of the Pagoda is where the Masters of the three cheese schools meditate and study. These Masters are far too wise to go for conventional bait. Instead, a hunter will need to craft very specific bait in order attract each master."
The mice found in the Meditation Room are the, Master of the Cheese Belt Mouse, Master of the Cheese Fang Mouse, Master of the Cheese Claw Mouse and Hapless Mouse.
