Klutzy has been the only mascot so far whom the Club Penguin Rewritten team have explicitly confirmed will not be visiting in celebration for the game surpassing ten million registered users. This is because Klutzy’s in-game sprite will be updated before his next visit.

It’s still a mystery which characters will visit, with Herbert being rumoured to attend since it’s been so long since he’s appeared! However, given this is the only definitive information regarding mascot visits so far, I felt it was worth sharing for those hoping he would appear.
The Klutzy tracker has been updated accordingly.
