This looks an awful lot like some other useless Wii accessories out there already, but it’s Nerf so they’re extra squishy and supposedly safe.
The Nerf Sports Pack includes a Nerf foam sleeve for the Wii remote and three Nerf sports attachments–a foam golf club, baseball bat, and tennis racket.
See? Safe. But I’d rather Nerf stick to making huge foam dart-shooting sniper rifles.
