In a blender, combine strawberries and 7UP, and blend until smooth. Pour into another container and set aside.

Rinse out the blender and combine pineapple juice, cream of coconut, ice, and banana. Blend until mixed and frothy.

Fill bottom third of a mason jar with strawberry mixture. Tilt glass and gently pour in the pineapple coconut mixture. The two flavors will look mixed, but if you wait a bit you will notice the colors/flavors separate, with the strawberry rising to the top.

Garnish with a skewer filled with blueberries.
