I find the megaphone works really well for finding Joan. I have two towns and was busy buying turnips in one and selling in the other, and every time I came back into the turnip town I was able to find Joan easily, even when she was hiding behind buildings.
Rosie. I have tried pronouncing her name many different ways (roh-see, roh-zee, rose, and ro-si-e) and I usually end up calling Wolfgang instead, and occasionally I get Francine (ross-ee, rozz-ee). Someone here managed to call a villager using their Japanese name, but yet again Wolfgang responds to Bouquet. He just seems really sensitive, because if I don't speak clearly he's usually the one that responds. I have to go slow and put a lot of emphasis on FRAN-cine, because just speaking her name normally tends to call Wolfgang.
Sometimes I wonder if the game is just getting confused whenever Wolfgang is outside. However, I'm pretty certain that when I called Rosie while both Wolfgang and Francine were somewhere else, I didn't get any reply at all. Unless the game is defaulting to Wolfgang even when he's not outside (perhaps someone should do some testing on this with villagers they're willing to lose), I'm wondering if Rosie herself is the problem; some people claim that you have to intentionally mispronounce Phoebe's name to get her to respond.
It's frustrating because all of my other villagers respond perfectly, even Deirdre, whose name I wasn't sure how to pronounce but pinned down on the first try. For those with Deirdre troubles, have you tried saying "deer-druh"? It sounds like Deer Drum, but without the 'M'. It always works for me if she's outside. If that's not working for you, though, I'm sorry, but I don't have any more suggestions.
Even if the entire world despised me
If just one person needs me, I'll always be happy
"Wish this tool would have drop-menu so I can just pick name of villager/character I want to call out."
I agree. I don't use it cause I'm too nervous to say the villagers names. Plus I'm also afraid of people in real life saying "What did you say." or "Who said that." I will be so nervous I'll be sweating like its 110 degrees outside.
When Isabelle announces a moving villager she says its sad.
Its only sad when a dreamy moves out.... Happy when its not one.
