Lots of animals wallow to escape the heat of the sun. My animal expert 4 year old could probably ramble off at least a dozen. I will spare you that list, but here is my shorter version:
1. Elephants
2. Pigs
3. My sons and nephews

As I am sure those of you who know me know already- this was all my idea. Anything for a picture for my kitchen wall collage!
But really, what boy on this earth wouldn't jump for joy at being TOLD to have a mudfight??
