Pickle (PCL) was a program created by Rancidkraut in which a user could easily create bots for Clubpenguin with more simple codes rather than more complex coding in programs such as Perl. The name of the program came from it's beta name; PCL which stood for Penguin Client Library. He called it Pickle because when PCL was pronounced as a word it was pronounced as Pickle.
It was widely used by members of CPHQ to create a variety of interesting bots. Many CPHQ members quickly picked up the skill to write Pickle codes and soon making bots was very easy. Unfortunately the program is now obsolete due to the Clubpenguin staff totally updating all of their URLs and files meaning in order for the program to work again you would have to virtually change everything in the program.
