PEN BLOCK


                  The Pen blocks are green in colour. These blocks draw a trail as the sprite moves
                  on the stage. You can change the colour of the pen. In Scratch 3.0, you have to add
                  Pen blocks to the block category. To do so, follow the given steps:
                  Step 1     Click on the Add Extension button.

                  Step 2     Click on Pen option. The Pen blocks are added to the Code tab.
