So, this is my first year going ice fishing. And The first time I went out with an ice tent, my friend and I set up about 20 or so yards away from an overgrown island. It was a good day, caught some nice pike and perch, but then while sight fishing in the tent, I saw an odd head appear about a foot below the ice. At first I thought it was another Northern coming in for my lure, and then I noticed this pike had fur lol. Within a few seconds the Muskrat swam his way up my hole and my first reaction was to @#%^ myself haha. Fortunately I didn't, and he seemed to only come up for air. I was sitting there shocked for a moment considering I've not spent much time on the ice, I didn't know it was even a possibility that a mammal would come up for a breath while I was jigging lol. He managed his way back to the hole at least 4 more times that day, I wish I would've had a camera ready because it was pretty cool.

 So has this happened to anyone else, or is this an odd occurrence?
