This Tom & Jerry cartoon I just found and watched on the DVD of Billy Rose's Jumbo. It has a baby elephant stumble from a moving train to the house where the cat and mouse live. That elephant first goes in Tom's bed under his blanket before that cat goes there for his rest. I'll stop here and just say what happens after that is quite hilarious especially the way it all ends, that's for sure! So on that note, I highly recommend Jerry and Jumbo.
