Just look up pictures of Lolly's expressions, see if you find them cuter than Molly's, then decide. In the end they both have the same personality so it comes down to design.
I personally like Molly more. I like her height and she looks like an actually duck which is kinda neat. Tho I suppose Lolly is kinda more neutral in her colors, so she can match with pretty much any village or shirt. Tho her house is fairly loud, heh heh.
Idk, idc. I'm tired of all these "Marina or Lolly?" "Marshal or Pietro?" etc. threads. I think you should choose. If I were you I'd pick none, they're both so overrated.
But if I had to choose, Molly? Idk. I just like ducks better.
I haven't had either but based on pictures alone, I'd pick Lolly, though I think Molly is really cute as well. Objectively speaking, I think they're equally cute but cats are my favourite animal, so I prefer Lolly's looks for that reason
Before I pick a villager, I visit them in a friend's town or go to someone's Dream Town that has said villager. I would have to say Molly though. I've never seen Lolly, so of course Molly would be my choice.
Lolly was my bff in city folk so I just love her a lot. I was recently reunited with her too But I also love molly because ducks are too adorable. I can't choose really.
