This was definitely trickier than the previous two examples we looked at, and there was a significant amount of trial and error to get this functional. Specifically, having the turtle return to its original starting point was tricky as there was a bug where the turtle would glitch around the screen before settling on its end point, which threw me off for some time. Thankfully, I just began testing some different combinations one at a time until I achieved the desired outcome.
