Quick update on Mission 11, Club Penguin released the Club Penguin Times Issue #238 today, and with it one of my good friends, OreoSummit, found a note from Herbert. Here check it out:

After looking over the note, you realize if you take the first letter of each flag you will solve the puzzle! This is what the note reads once you get all the letters together:
DEAR PENGUIN
SILLY AGENCY
lOOK SHARP AGENT
I’LL SEE YOU ON MAY 18
- HERBERT P BEAR
Does this mean that Mission 11 will be coming out May 18th? We will just have to wait and see! Leave a comment and let me know your ideas!
