The reflection of the sun in puddle shapes that you see when looking out over a body of water on an overcast day and the sun is shinning through cloud openings onto the water in random spots.
As we drove past the lake I said to my friend Look at all those sun puddles.

A bright, warm spot on the floor or other surface created by the sun streaming through a window. The opposite of a shadow.
Cats love to bask in sun puddles.
