How do you think MV19 is going to adapt "Moominpappa's memoirs"? Because it seems like they're also doing the comet adaptation, so they are going to clash both¿
I doubt Gusty would have the gall to make a straight adaptation of Moominpappa's Memoirs so late into the series and somehow fit it into the plot of Comet in Moominland, or at least I hope they don't have the gall to do it in their 13 episode runtime.
They already referenced the story in good detail in the Golden Tail episode, they've already referenced Edward, the Muddler, the Nibling and Hodgkins, now we just need them to follow it through with something more substantial, because the show's viewers who haven't watched or read anything else of Moomin are definitely going to be wondering who exactly Muddler and Hodgkins are, and what the heck a Nibling is.
They've already used up the Ghost (or at least a character similar to it) and sent him to the aurora borealis in season 1, I can imagine that maybe they would, like, do a throwback to him but honestly who even thought about the 2019 Ghost in any substantial way after that episode? The creators don't even bother putting Emma or Ninny in crowd shots or give them small character bits past their respective episodes, so it's doubtful they'd being the Ghost back. It'd be redundant to have an episode dedicated to Moominpappa's backstory adapted into a stage play only for us to see a flashback version of it unless they really wanna go out there with it. The Joxter lacks even a peep of reference which is super weird so it'd be double weird to bring him in with Muddler and Hodgkins who have been mentioned, like, who the hell is that guy?
If they want to bring in Moominpappa's Memoirs in a way that feels more natural for the final season of a show they should probably just adapt the epilogue where they have a big family reunion, perhaps interweave Moominpappa's character into it and make him proactive in seeking out his old friends for the adventure and we'd get the adaptation through his reminiscing while the end of the world is ongoing, I think that'd be neat.
You could even sprinkle in a little heartbreak and say he's doing it for a proper goodbye because if they did in fact make Moomins and the Great Flood canon then that would make Moominpappa abandoning his family for years canon, and that could extend to him abandoning the Oshun Oxtra without warning because something something he was too selfish and he gets character development when he realizes how self-centered he's been and tries to make up for it.
Perhaps that would be the B-plot with the Moominparents instead of them staying at home waiting around like in the book while the kids go off on their mountain-trotting adventure.
Honestly I just want Sniff's character arc to end with him finding his proper parents who care for him along with getting the cat he adopts in Comet in Moominland. Everyone else has been very rude or disregarding him throughout the show, that was even his main thing in season 3, so it would mean the world to me if he just. Gets a Happy Ending.
What I'm most worried about in an adaptation (adjacent) of Memoirs is the infantilization of the Muddler, everything else is either already gotten down by the show (Moominpappa's character) or difficult to mess up unless they're actively trying to (Hodgkins and Joxter's characters) but Muddler........ It's already a problem within the fandom and we know Gutsy and Moomin co. do cater to the fandom quite a bit. Maybe it's just that he's my favorite character ever but I am. Worried about him. Especially considering characters like Sniff or Toffle.
But like, yeah, you can do alot with Moominpappa's Memoirs but I doubt Gutsy writers have the imagination or brain power to manage it alongside a Comet in Moominland adaptation some the likely adaptations of the comics or original plot episodes. That episode based on Moominvalley in November is the most egregious thing they've done in the world as an adaptation and I hope they don't stoop down to that again but, yeah.
It really sucks that the showrunners weren't sure if they were gonna get past season 2, they could've done alooooot better with the show's plot and character arc structure and I'm sceptical about the quality of a simultaneous Comet in Moominland and Moominpappa's Memoirs adaptation for the final season. But we'll see.
