This is based on the game, Mario Unleashed.
The title screen shows up when revealing Luigi's mansion, under the name, Boo House. Mario, Toad, and Luigi are walking to the mansion, when two ghosts (posibly Ron and Flippy) and a girl ghost (proboly Rosalina) look at a picture of a green Toad and three red Toads screaming and then Ron, Flippy, and Rosetta (Rosalina in North and South America) laugh.
MORE KOMING SOON!!!
People think there is no diouloge and SMB effects in this. But the pipe effect appears when Mario is saying "Mama mia!" when he enters the mansion , and the Game Over effect was when Mario says "I'm-a sorry!" after scaring Luigi and Toad. Luigi is tied to a chair in the ending, saying "Help-a me!"
