ORIGINAL STORY 11.00am:Nintendo platformer New Super Mario Bros. U Deluxe sold 25 per cent more boxed copies during its Nintendo Switch launch week than it did on Wii U.
The introduction of Peachette has been responsible for all sorts of things: internet memes and disturbing fan-art aplenty, sure, but also the removal of Blue Toad as a playable character.
Remember Bowsette? The viral fan-created character combination of Bowser and Princess Peach was one of our moments of 2018. But Bowsette was only ever a fan-creation - and despite Nintendo fans' hope she'd someday be made canon, Bowsette will stay that way.
It's been a busy couple of weeks for Nintendo's characters (and their disturbingly eroticised hybrids) on the internet. First there was Donald Trump's penile Toad, then Bowsette, and now the latest Mario universe star hovering on the brink of meme-dom: indie rock Rosalina.
Unless you've been living under a rock this past week, you'll have seen Bowsette during your internet travels.
Last week, a new item for New Super Mario Bros. U Deluxe was unveiled which created a brand new character in Mario lore. The power-up, called the Super Crown, appears to transform Toadette into a Princess Peach fusion called Peachette - and understandably, many Nintendo fans were utterly flummoxed. Is Peachette an entirely new character that only appears with the crown? Or is the crown able to transform any Mario character into a Peach version?
Blink and you'd have missed it in last week's Nintendo Direct, but we got a brief glimpse at a brand new Mario character. Her name's Peachette, and she has got Nintendo fans very confused indeed.
