Nintendo has eyed adding a Playdate-style crank to the Switch 2, according to a recently spotted patent from Nintendo Patents Watch. The hypothetical accessory would add tracking rotational movement to an existing bag of Joy-Con 2 controller tricks that includes motion and mouse controls.

Based on the patent application, the crank accessory attaches to the side of a Joy-Con 2 magnetically, not unlike the controllers’ wrist straps. Whichever game supports the accessory can use the Joy-Con 2’s mouse sensor to track the rotations of the crank as an input. Fishing games or games with dedicated fishing mini-games, like Animal Crossing: New Horizons, seem like the obvious contenders for an accessory like this, but knowing Nintendo there are weirder possibilities, too.

Another patent imagines a similar setup being used for a clickable wheel. The patent illustrations looks like a lighter, but the accessory could just as easily be used while dragging a Joy-Con 2 along a surface. It might even add extra resistance or friction to the Switch 2’s mouse controls.

Given that these are patent applications, there’s no guarantee Nintendo plans on turning either of them into real products. Still, they’re a glimpse at the Switch 2’s untapped potential for supporting goofy accessories, something that defined a good portion of the Wii’s lifespan.

The wildest Nintendo got with the original Switch was Nintendo Labo, cardboard accessories that turned the console into everything from a VR headset to a simple fishing rod. A crank might be the first of several adventurous accessories for Nintendo’s new console.
