epic snowman built- but what do i class it as for cardio

just a little fun one....yesterday i spent the better part of my day off in my garden with the dog (ok only using that as excuse) and built a snowman. He took me hours to do and i can hardly move today- who needs a gym HA. I managed to make a human sized homer simpson and it was fantastic if i do say so. Had great fun doing it and to my amazement he is still standing. I was wondering what other people do in regards to adding activities that would seem rather strange into mfp or do most of of you go MEH--forget about it????? any thoughts
