Cadence made an appearance on the server Zipline on Club Penguin Rewritten today, the 27th of June, where she gave out a hard difficulty stamp and background.
The background was the same as the one which you could obtain by clicking the bot of her at the Waddle on Party. You can view it on a playercard here.
Most of this visit was tracked by the tracker! She likely will return, and DJ Maxx will also visit the island soon!
Good luck meeting the mascots at this year’s Music Jam!
