I was pretty bored, so I decided to mess around with pen! I found a great project ( Linked in the notes and credits section! ), and found a weird block that changes the shade of pen, which I put in my backpack and messed around with it here. This is how it came out! ( Wow! It also has only 24 blocks! :o )
The project with the shade changing block, which I was also greatly inspired by is... Mysterious Pen by @gloom- https://scratch.mit.edu/projects/127577570/ Also, this project gets pretty laggy toward the end, so you can restart the project to see it again and take out the lag! Enjoy! :)
