Problem Statement:
The pre-placed blocks will draw part of the umbrella. Edit the first loop so instead of 2 light blue circles, 5 circles are drawn to create the bottom edge of the umbrella. The raindrops are currently circles. Add triangles on the top halves of the circles to create the proper raindrop shape.
