When I entered the level, other than the music, everything seemed to be the same, except for the fact that the little Koopa that slides on the ledges wasn't there anymore, nor was the Banzai Bill. The Dragon Coin was still there; however, for some odd reason, I wasn't able to collect it, or rather any Dragon Coins at all. The author made certain of that. I also noticed that there was a brown used block near the spot where the Banzai Bill normally shows up. I can only assume this was a revisit to the level after I had beaten it like I heard in some half-assed creepy stories in other Mario games. Now I was wondering why things were like this, making me wonder about the intro message. Had Mario done something previously to Dinosaur Land? Was this from Bowser's point of view? I quickly dismissed the latter option, because it seemed kind of stupid. So that left me thinking that Mario at one point in time in the author's story did something, but what? What did Mario do?
