Slice bananas into 1-inch thick rounds. Slice off stems of strawberries and then slice them in half from top to bottom to form a triangle-like shape. Cut a few pieces of the carrot into small matchsticks; cut the remaining carrot into sticks.
Have children skewer a strawberry for the hat and banana slices for the snowman body. Use raisins to form the eyes and buttons; use pieces of carrot for the nose and arms.
