Ashley's Mansion

Ashley's Mansion is a haunted mansion located in Diamond City, which is seen in the WarioWare series, first appearing in WarioWare: Touched!. It is seen in every WarioWare game where Ashley appeared. It is a notable location in Ashley's Theme from WarioWare: Touched!

WarioWare: Touched!
Ashley's Mansion is portrayed as a spooky place, with the interior being decorated with skulls and the illumination done by candles. The house is surrounded by dead trees and constant thundering clouds. Only one microgame is played inside it.

WarioWare: Smooth Moves
Ashley's bedroom and the mansion's library are shown for the first time in WarioWare: Smooth Moves, with all microgames taking place inside the latter. Chatty Mr. Spell Book and Monster Flower are newly-revealed residents of the mansion.

WarioWare: D.I.Y
The mansion appears only in a black-and-white introduction of the Ashley's stage in WarioWare: D.I.Y.. All microgames take place outside it, among the dead trees.

Game & Wario
Ashley's Mansion returns in Game & Wario, in the introduction of the minigame Ashley. Its exterior is the same as its previous appearances. The library is the only room seen in the scene.

Web comics
In a comic strip on the Nintendo Kids Space web portal, titled Ashley no Halloween Night, Ashley is shown to reside in a differently looking domicile. Referred to as the "House of Magic", it has a castle appearance with multiple towers and red rooftops.
