According to voice actor Jacob Craner in an interview with Zelda Universe, he said the inspiration behind his voice of Robbie in the English-language dub was American actor Jack Black's performance in the 2006 film "Tenancious D in the Pick of Destiny", which Craner claimed he was obsessed with when it first came out. In addition, he said that during the audition process Nintendo localizers told him to give the character more of a cliché and stereotypical "nerdy scientist" affliction. However when it came time to record, they changed their minds and instead wanted the character to sound like a "crazy rocker" type of character, thus having Craner lean instead toward his Jack Black impression.
