I caught this little muskrat ramblin' around our pond.
At one point, you can see him dive and then come up with an old lily pad draped over his head like a hat.

Other things to watch for:

Notice how his tail pops straight up out of the water when he's going for the goodies on the pond bottom.

Also, near the end of the video, he gets a surprise when another muskrat (or beaver?) shows up!
