If you’re a fan of Super Mario, then this is the mouse for you. It’s a Koopa Shell, available in either red or blue, and it comes with a matching mouse pad. This is an actual working USB mechanical ball mouse with scroll wheel and it’s compatible with PCs or Macs. It doesn’t even require any special mouse drivers. I triple dog dare you to get one of these and use it at the office. I bet your boss will never take you seriously again.
