Vincenzo says in Italian "Io sono la balena" and Sophia translates this to "I am the walrus." But it actually means "I am the whale."
In this episode Dorothy and Blanche are awakened by a stench coming from the kitchen. After they go to inspect, we see that Rose is making some sort of Krispies treat. As you see her carry the plate to offer Dorothy and Blanch one, you can see that there are at least three very small "Krispies" on the plate. And once they all start to eat them you can easily see that none of them are actually picking anything up and putting it in their mouths when they reach for seconds.
