Mops has zero qualms about aliens and will actually be more inclined to like these just because they have no context for her and aren't afraid of her.

She will be happy to talk at length about where she comes from and ask about thessyx cities. I'll be real it's gonna involve a lot of infrastructure, the problems of keeping amphibious spaces clean, how do they dispose of waste. Mops can bond like a motherfucker over that stuff if she can find anyone who's worked in related fields.

If she can make friends with some she'll ask after them in future interactions.
