This Friday, the 19th of December, Spanish Club Penguin Team member Karlapop321 will be holding a meetup to unlock the Play It Loud! stamp, or in Spanish, ¡Sonorífico! The meetup is at 7:30 AM PST on the Spanish server Avalancha.
The meetup is, of course, at the Lighthouse since that’s the room you can unlock this stamp. Make sure you wear a musical instrument and play it!
Nah, already got the stamp
