A long time ago I did something similar to this in the bathtub and my kids LOVED it!  So instead of bath time with shaving cream and Arctic animals it was painting time! I flipped over a blue storage box I had, put some shaving cream on the top with some  Arctic animals and gave my kids paint brushes and more shaving cream to paint “snow” on the animals for the snowy day! My kids went back and forth several times rinsing off the animals in the sink so they could paint them again!
