Pen blocks basics: Pen down

To start drawing with an actor, use the pen down command. As the actor moves on the Stage, it now leaves a trail behind it. Try reading this code first:

Try walking like this actor before you run your code! Yes, stand up and get some exercise. Say these instructions aloud and act them out.

Walk 2 steps (unless you have enough room to take 200 steps!), turn 90 degrees, then repeat it another 3 times. What shape did you walk? Try drawing it on pen and paper.

Finally, run your code in Tynker, too, and watch the actor move.
