Susheese
From MHWiki
This is expected to be the next type of cheese availible on MH. Apparently the key ingrediant of the cheese is mutated fish found in the Burroughs River and the cheese will be used to attract rare mice in the Training Grounds or a future area in the Furoma area. Speculation is that this cheese will require the catching of fish (either in the river or from mouse drops) and adding that to an existing cheese.
