The Pen extension is a Scratch 3.0 extension allowing sprites to control their pens, as well as stamp themselves onto the stage and remove all pen marks. Before Scratch 3.0, these blocks weren't an extension, and were located in a category called Pen Blocks.[1] To use them, they must be enabled in the "Extensions" section of the editor. Older blocks are kept but hidden.[2] There are 9 blocks. Pen blocks are useful when creating a one sprite one script project, allowing one to take various actions:

  • Stamp the sprite
  • Put the pen down
  • Release the pen

One example of a one sprite one script project is a simple drawing program. Pen Blocks can also used to make Games and Simulations, as well as other things.
