 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 .
