Nintendo Today App Update Sparks Donkey Kong and Mario Kart World DLC Rumors

Nintendo has once again ignited conversation within the gaming community following a significant update to its Nintendo Today! app, introducing a suite of new themes centered on beloved Donkey Kong characters.

This update comes on the heels of Donkey Kong Bananza’s successful release, and notably showcases artwork inspired by Bananza, the latest entry in the iconic platforming franchise from Nintendo.

Since its debut, Bananza has reinforced the enduring popularity of Donkey Kong on Nintendo Switch and the digital eShop. What has truly caught fans’ attention is the announcement of an exclusive King K.

Rool theme, set to unlock for app users on December 15, 2025.

King K.

Rool, the infamous antagonist and long-time nemesis of Donkey Kong, was kept under wraps for most of Bananza’s promotional cycle, only revealing his role as the final boss at the conclusion of the game.

The secrecy around his appearance adds to Bananza’s reputation for surprise and delight, characteristic of Nintendo’s approach to keeping players engaged. The excitement does not stop with new themes.

Observant fans have discovered that both King K.

Rool and the enigmatic Void Kong are credited as voice actors in Mario Kart World’s credits, despite neither character making a direct appearance in the roster at launch.

This detail is noteworthy as Mario Kart World launched prior to Bananza, making their inclusion in the credits unusual.

The speculation connecting the December 15 date stems from the coincidence of The Game Awards 2025, a high-profile industry event where Nintendo has previously unveiled major downloadable content (DLC).

Notably, the first DLC character for Super Smash Bros.

Ultimate was revealed during The Game Awards in 2018. Nintendo has a well-documented history of leveraging large industry events and online updates to introduce new content and maintain player engagement.

While Nintendo’s presence at The Game Awards is not guaranteed, the company has broken patterns in the past to deliver surprise reveals.

With Mario Kart World’s strong performance – recently topping the UK physical charts yet again – and the Switch 2 reportedly moving over 6 million units within its first two months, the possibility of high-profile characters such as King K.

Rool and Void Kong joining Mario Kart World as DLC remains a tantalizing prospect for fans, even if official confirmation is pending. For now, speculation continues to build, fueled by credible in-game credits and the strategic timing of the Nintendo Today! app update.

The gaming world will be watching closely as December 15 approaches, eager to see if Nintendo has another surprise ready for Mario Kart World fans.
