Paint By Letters was a game in Club Penguin Online and also a book series found in the Book Room's Library on the Old Client.
Gameplay
The game was about typing. In the three stories, you had to type the whole story on your keyboard. Sometimes, you had to make a decision, which would change the course of the story. You received bonus coins if you found all the hidden coins in the books (800 coins in total). Almost every page had a hidden coin. Some were quite difficult to get.
