I recommend Club Penguin Journey! That server uses the Gen 2 art style and kinda does their own thing. I've seen jack-o-lantern and grey sensei puffles! They recently hit 100K registered accounts too, so they're growing pretty fast!
There are fan versions of club penguin called new club penguin and club penguin imagined, which are the exact same as the old version that disney made the only difference is that you have to download both versions I mentioned because flash is no longer available.
I remember asking my grandma how to spell penguin after someone recommended me the game by word of mouth in 2007 and she spelled it PinQuin 🥲 but I got in there eventually. I was only 6 or 7 so writing and spelling was still not that good 😅
