To any of the mary fans, Animal crossing maple leaf has brought to you: The warp pipe house (entrance....)
Rsetti correntlly uses a orange warp pipe as the entrance to his house. This is commonly used for mario fans.
The warp pipe house looks like a green warp pipe from the mario series. Once you go inside it has an appearance to that of the underground stages in the mario world. The red warp pipe sends you to the basement, while the blue warp pipe sends you to the attic
