9-Volt's House

9-Volt's House (known as 5-Volt's House in WarioWare Gold) is the residence of 9-Volt, 5-Volt, and Fronk in the WarioWare series of games.

9-Volt's bedroom is the most frequently seen room, being the only one to appear up until Game & Wario. Since 9-Volt loves video games, his bedroom is scattered with video game consoles from the past and present. In WarioWare: Twisted!, 9-Volt invites 18-Volt to his house to play his NES.

In WarioWare: Touched!, 9-Volt and 18-Volt play their latest games in his bedroom. In WarioWare: Smooth Moves, 9-Volt again invites 18-Volt to his house, but this time to play a Game & Watch.

The house is the main setting of the Game & Wario minigame Gamer, hosted by 9-Volt and 18-Volt. 9-Volt's mode takes place inside his bedroom, while the house can be seen across the street during 18-Volt's mode.

The house reappears during 5-Volt's stage in WarioWare Gold, in which 5-Volt watches Mr. Sparkles' bodybuilding exercise on their television.

In WarioWare: Get It Together!, 9-Volt and his Fronk pet play his Epic Augmented Reality Game past his bedtime in his room without 5-Volt knowing. Additionally, 9-Volt's House appears during the cast credits for this game, in the background when 9-Volt, 18-Volt, 5-Volt, and 13-Amp are credited.
