It’s hard to get a lot of conversation going because i find that most guests with Duffy and friends Merch (another aside it’s overwhelmingly Lina-Bell and Stella-Lou, I’ve never seen cookie-Lyn, olu-Mel or gelatoni, Duffy and Shelly-may are pretty rare) don’t speak a lot of English but from what I can gather Chinese, Korean and Taiwanese seem to mostly get it from Shanghai, Japanese is split between all three but slightly biases Tokyo and most people who have said HK have also mentioned getting it from the airport store as much as from the park itself
This is across a sample of maybe 120 or so people who I picked up on their Duffy Merch and they could speak enough English I could get enough info to have a conversation
