over time. Prior to the SpotPass suspension, several Special Notifications sent from Nintendo based on special occasions featured Nikki announcing such occasions, such as Valentine's Day, and these notification messages often came with new non-game-based stationery and AR pictures of Nikki. Nikki's official Mii would also automatically appear in the StreetPass Mii Plaza when these messages were opened. Nikki's name is based on the app's Japanese title, which features the term , which literally means "diary" in Japanese. As a character, however, Nikki's Japanese name is written in Kana characters () instead of Kanji. Due to the character's popularity, Nintendo had released another Nintendo 3DS app featuring Nikki called , although the app was exclusively available to members of the Japanese Club Nintendo rewards program. After the discontinuation of Club Nintendo in Japan on September 30, 2015, the app is no longer redeemable. A Nintendo 3DS HOME Menu theme based on Swapnote called "Swapnote: Nikki and Friends" was released in Japan and North America. Nikki badges would occasionally become available in the Nintendo Badge Arcade app for Nintendo 3DS as part of the "Nikki & Friends" set. The app's host, Arcade Bunny, often expresses his infatuation towards Nikki. Nintendo of America originally used Nikki's physical appearance as a Mii Fighter to market Super Smash Bros. for Nintendo 3DS and Wii U. Nikki is included in the Wii U version of Super Mario Maker as an unlockable "8-bit" costume. Nikki returns as a host in Swapnote's successor, Swapdoodle. Nikki appears as an assist trophy in Super Smash Bros. Ultimate. Swapdoodle Swapdoodle ( in Japan), the successor to Swapnote, was released as a free-to-start downloadable title in North America and Europe on November 17, 2016. The series retains several features from the original Swapnote, with the exception of photo and sound attachments, while adding new features including Doodle Lessons, stamps, secret pages. The application can be expanded with purchasable downloadable content, which adds new pen colors, stationery, note capacity and lessons. Reception Despite being a successor to PictoChat, Swapnote's messaging model is not based on the standard instant messaging model as PictoChat had been, as the application lacks instant messaging features such as keyboard functionality, chat rooms, and live-continuous messaging.
