For the record, I don't know what that red line was across the bottom. It's not visible in-game since it's out of bounds and the camera never pans that far downward under normal circumstances, but it kept showing up in the map viewer, so I included it anyway. Also, I know Bo Peep looks dismembered, but that's because part of her body is apart of the background and other parts are separate sprites.

Fun Fact: The bricks behind the drain pipe are not visible in-game under normal circumstances. However, by using a jump-in-midair cheat from Gamehacking.org and going above the map ceiling, the camera will go down to the bottom of the level, allowing me to rip the normally inaccessible areas as it does.
