They are really Cousions

MacytheStrange This isn't actually 'proof', so it shouldn't be stated as such. And actually I think the King of Arendelle and the Queen of Corona look similar if anything. But I don't really go for the idea of them being cousins. Oh, and you misspelled 'cousins' in the title. Just saying. :)

fiina I agree, it can't be said they're cousins. Actually in my opinion Anna, Elsa and Rapunzel do look somewhat alike so they could be cousins but I think their fathers could be brothers. To be honest their mothers doesn't look like each other to me at all. I think Anna's and Elsa's mother look more like she could be Rapunzel's and Eugene's daughter but it's just me.

TigerRanma Yeah, I don't think their mothers look similar either. Just because they have brown doesn't mean they are sisters. Hell, the "cousins" look more like sisters than the moms do.
