Talk:Bowser VS ???/@comment-26458478-20160319013537/@comment-2255534-20160319040833

One big thing they forgot about was that as Bowser was holding the cannonball, he was hunched over. When standing up, and then compare the ball, I personally estimated it to have been closer to 30 feet in diameter.

With that in my mind and using their (very helpful) volume calculating source, I personally found that the cannonball weight just over 3000 tons. Not quite as impressive, but sure enough, you're right. That actually does beat out the train feat.
