 In preparation for presenting Crash Bandicoot to Sony 's Japanese division , Gavin spent a month studying anime and manga , reading English @-@ language books on the subject , watching Japanese films and observing competitive characters in video games . Upon Naughty Dog 's first meeting with the executives of Sony Computer Entertainment Japan , the executives handed Naughty Dog a document that compared Crash with Mario and Nights into Dreams .... Although Crash was rated favorably in the graphics department , the main character and the game 's non @-@ Japanese " heritage " were seen as weak points . The renderings of the character made specifically for the meeting also proved unimpressive . During a break following the initial meeting , Gavin approached Charlotte Francis , the artist responsible for the renderings , and gave her fifteen minutes to adjust Crash 's facial structures . Sony Japan bought Crash for Japanese distribution after being shown the modified printout . Pop @-@ up text instructions given by Aku Aku were added for the Japanese version of the game .
