I was a lil curious on what he would look like in a winter setting and this is what I came up w/, a lil bit of an idea what I was thinking.

Scene: A brave lil mouse travels through the harsh blizzard trying his best to continue but soon collapses fearing this might be the end as he falls asleep; he soon awakens to see light through the snow as he then pushes and pops out to see his body was covered in thick white fur more fit for winter and his nose is black, he is lucky his body adapted so quick in that climate.
