Nah I’m sorry, Yavanna’s children are canonically Ents, not Hobbits. The Yavanna-made-Hobbits thing is fanon, I am sorry to say. It’s SUPER adorable tho, it’s cute to think that the wife of Mahal had her own little hairy people and that they’re all parental of both, but yeah – Hobbits are an offshoot of the race of Men, and they go to the same afterlife as Men. And Yavanna doesn’t. Like. Dwarves. At. ALL. (they chop down trees!). *wince* idk, I like the fanon idea, it really is sweet! But the books don’t groove with it at all, sadly.
I sort of like the Hobbits-go-to-Mandos thing as well! CAN YOU IMAGINE, snrk. Mr. Mysterious Doomsman of the Valar meets say, Pippin. Bwaaahahahah.
Awwwww, Custard would. Also, I expect Bilbo would fuss and curse about all that blasted cat fur (”it gets everywhere!”) but would secretly slip Custard little bits of fish when nobody was looking, ❤
