Splatterhouse: Wanpaku Graffiti (スプラッターハウス わんぱくグラフィティ?, lit. "Splatterhouse: Naughty Graffiti") is the second game to be released in the Splatterhouse video game series. Unlike the other games in the series, Wanpaku Graffiti was released only on the Family Computer and is Japanese exclusive. It is also the first Splatterhouse game to be released for a home console.
The game itself differs from the other Splatterhouse games, in that its characters are "super deformed". It also takes a comical approach to its presentation, parodying horror movies and by incorporating other pop-culture references related with the genre into itself.
