Cut 3 pieces of pineapple into about 2 inch long strips, about 1 - 1.5 inches thick. Cut two of the stripes into long triangle shapes. Arrange pineapple into lightning bolt shape (with the two triangle pieces on either end). Secure with toothpicks. Place lightning bolt onto a long skewer.
Cut fresh strawberries into 1 inch thick circles. Place on skewer. Add blueberries to the centers of the strawberries, securing with toothpicks.
On last skewer, add green grapes, circle slices of banana and raspberries to create "traffic light" skewer.
Combine one banana, 1.5 cups frozen strawberries and 1 cup of strawberry yogurt. Blend until smooth.
Place smoothie in cup, adding 3 fruit skewers.
Cut top off one strawberry. Cut slit down center of strawberry, lengthwise. Add two chocolate chips to bottom end (as tires) & press in, using peanut butter to help hold in place if desired. Carefully place strawberry "car" to the rim of the smoothie cup.
Serve immediately. Refrigerate or freeze leftovers.
