I recently remade 7/10 of my pets :o) and even got an 11th! But that's a big minion overhaul. I now have a Nostalgic Noktoa named Domiduca and I've never been good at picking minions. There don't seem to be a lot of toy-themed ones :( ...
Domiduca herself is a Roman goddess of marriage. Her duty was to protect children, especially lost children, and help them find their way home. A toy minion rather than a birdie minion would be better. Help? ❤️
So far, I like: I also have a I suppose I could use, but I want someone to buy it.
But like I said, I'm terrible at picking things and there are so many minions on the site!!!
SIDE NOTE: My Sweetheart pet has a Queenie, but would a Tinker look cute w/ him? :O opinions welcome !!
I know you mentioned a toy minion is better but since she's a roman goddess of marriage I could see her with:
Bellow:
Canty:
(but a bit pricy)
Chibby:
Shy Mouse:
Cheridon:
(very cheap!)
Dawnfluff:
(because it looks like a love spirit dragon)
Greedy Guts:
(funny character, I imagine him a goofball)
Since she's nostalgic that can cover the toy factor, so I thought candy/sweetheart would fit too since she helps lost children. Kids love candy :) I love candy too. Heehee
if you're going for toys, maybe or ? These seem to incorporate both the love/marriage theme as well as the toy thing. :) I thought of as well though

Perhaps this page on Subetalodge will give you some ideas? Here's a couple suggestions that I got from looking at this link:
You gave me so many suggestions, thank you! I love the Bellow and the Dawnfluff :)
the Ichbit would be a great snatch from the Token Shop, and I adore the Lovely Muse, but it's so expensive :( :( I don't have near enough recycle points to buy her, LOL. So worth saving up for, though!
I looked on the SL, just not very well I suppose. :P I love the Pinhart! And I love your artwork/avatar :)
You guys have given me some A+ suggestions and things to save up for, ty so much.
