Pastry cart?

Fin is always saying the funniest random things. A few weeks ago he told Byron at breakfast "Finley and the two worms are on vacation so that's why the pastry cart and me are here." First of all who is he at that moment? We have no idea. Secondly, I have no idea how he knows about the deliciousness that is a pastry cart. Sometimes I wonder if he has a secret life or something.
