Peel orange and add to blender. Add 2 of the bananas to the blender with the mango; top off with orange juice and protein powder. Blend well. Add more orange juice while the smoothie is blending if it becomes too thick. Pour into another container and set aside.

Prepare the second layer by adding yogurt, berries, the remaining banana, milk and flaxseed to the blender. Blend well until smooth. Add more milk while the smoothie is blending if it becomes too thick.

Layer the smoothie mixtures in glasses. Use a butter knife or popsicle stick to create designs inside the glass if desired. Top each smoothie with a toothpick filled with fruit for added fun!
