This is one of my favorite animated shorts, and I would say it "builds the kingdom" for the very simple reason that it's about friendship. I don't think the fact that it's an advertisement detracts too much from that, but feel free to disagree.

This one is just for fun. I found it today and thought it was hilarious. It has to do with themes of creation/creativity, but in terms of religion could be seen as a bit irreverent.
