He spots the puppies examining his snowmen, and wonders if they are going to end up with yellow spots on them.
Looking closer at the dogs, he sees that what he thought were canine sweaters is actually just...really oddly colored fur. One appears to have purple fur with blue...paisley printed on it. The other is a purple and yellow plaid.
Poor things.
He makes a snow dog near them, to see what they will do.
