Earlier today, the Club Penguin Rewritten team released a sneak peek showing the left half of the Snow Forts during the Submarine Party! For what it’s worth, the sneak peek seems to depict a virtually identical design to the same room at the event on classic Club Penguin in 2008.
So far, based on this sneak peek and the one of the Coffee Shop, it’s unclear if there’ll be any “custom” rooms for the event. That being said, it’s worth noting that this is still going to be the biggest event on the new HTML5 technology.
The event will be beginning later this week, and more details can be found about that here. If any other sneak peeks are released by the team, I’ll be sure to let you know!
