Seriously. It even has a "portals scene" and this was meant to tie a perfect bow on the entire series, and does it. Everything is explained, every character who isn't dead is brought back, every story comes to a complete end and it even involves an honest to God battle at the end against the final boss of holiday specials.
TLDR summary: thousands of years ago the evil, godlike being Winterbolt ruled the universe and along with a dragon he turned everything into a lifeless wasteland of snow. Then, Princess Boreal comes and defeats him, sealing him away in a mountain, but she knew he would awaken again as she was exhausting all of her power to keep him imprisoned, and she's slowly dying. So before she dies, she basically triggers a series of events that spawn Santa, Rudolph and Frosty who act as vessels for her power (no seriously!) so they can come together someday to defeat Winterbolt when he awakens. Eventually Boreal dies, and Winterbolt is freed, and now they have to defeat him in what I can only describe as a reproduction of the final battle of Endgame but with puppet characters. And yes, there is a "sacrifice myself to save everyone" part and yes also an "every character steps out of the portals" part right before.
Absolutely brilliant. A little long, but it says it all. 9/10, I watch it every Christmas and so should you.
