Self-destructing messages

:For the plaque with a countdown in the Gadget Room, see Self-Destructing Message.
Self-destructing messages were hidden messages (sometimes in Tic-Tac-Toe Code) that were sent by the Penguin Secret Agency. They were only visible to agents, and often contained updates about investigations. When closing these messages, they would destroy themselves, either by crumpling up and exploding, or by a miniature paper shredder that appeared and shredded the message. The first self-destructing message instead burned a hole through the page (this did not affect the following page).
Most messages were labeled as "this message will self-destruct" although some did not, and instead would self-destruct when the message was closed by clicking the X button in the corner.
==Messages==
The first message appeared in issue 37 of The Penguin Times. Unlike later messages, it was publicly visible and not hidden. Starting from the message in issue 58 of The Penguin Times, messages appeared by clicking something on a page, and could only be accessed if the player was an agent. The message at the end of Avalanche Rescue is the only one to not appear in the newspaper.
For more detailed information, translations of encoded messages, and conditions to make the messages appear, see each respective Club Penguin Times issue article, which are linked to in the middle column.
