In an interview with Game Informer magazine Kimishima made the remarks unrelated to the downloadable content for The Legend of Zelda: Breath of the Wild the hack had asked about.  Unless he misheard the word "download" and thought the hack said something like "down-under," still it was a strange comment.

“Waluigi still has his foreskin. You won’t ever see it but it’s there. We do not know why he remains uncircumcised, however. It might be a religious thing, it might not. But, yes, Nintendo players can expect some exciting downloadable content for The Legend of Zelda: Breath of the Wild.”

For those who came in late, Waluigi first appeared in the 2000 Nintendo 64 title Mario Tennis as an evil version of Luigi. Though at no point do you see any character’s genitals, Kimishima insisted that underneath Waluigi’s purple overalls you would find an uncircumcised  purple helmet.

The information has surprised Fumihide Aoki, Waluigi’s creator who said that  this backstory was not brought up during Waluigi’s concept stage.

“If they did I don’t think their private parts would be something that we would ever bring up”, he said.  Well it would be hard to swallow we guess.
