The development of
Grabbed by the Ghoulies began in 2000, after the completion of
Banjo-Tooie. The idea for the game began with the name, which is a
pun on "goolies", a British
slang term for "
testicles". Before any details of the game were publicised, it was rumoured that
Grabbed by the Ghoulies would be the subtitle to the next
Conker the Squirrel game. After Microsoft purchased Rare for
£375 million in 2002, development of the game for the
GameCube was delayed until Rare converted it to the Xbox console. Development of the game took under three years. It was originally conceived as a larger, non-linear open
platform game for the GameCube. However, a simpler design and simpler concept were adopted due to the Microsoft buyout and increasing time constraints. After Microsoft's purchase of Rare, the studio re-affirmed their "simple design" of the game so that players would be able to easily adapt and devote less commitment to it. In a retrospective interview, Mayles stated that the change from GameCube to Xbox was difficult and required a lot of changes as
Grabbed by the Ghoulies was "an original game that started life as a Nintendo product". According to Mayles,
Grabbed by the Ghoulies was not inspired by Rare's similar-themed
Atic Atac. The
cel-shaded art style and design of the characters in
Grabbed by the Ghoulies were inspired by
Hanna-Barbera cartoons, and the various character personalities were based both on historical figures and people from Mayles' childhood. Antagonist Baron von Ghoul was "a mix" of the
Red Baron and British aristocracy, whereas supportive characters, such as Ma Soupswill, were loosely based on staff from a school. Mayles considered the conversion of the game to the Xbox to be one of the hardest challenges during development, as Rare had less than a year to finish the game once it was converted. == Release ==
