We knew Nintendo‘s Super Mario character (and friends) were incredibly popular worldwide, but who knew how many gadgets and toys they’d spawn? We’ve shared the Mario Race Track, Remote Control Racer, solar toy and keychains with you. Now comes Mario and Invincibility Star USB two-button mice, with a roller ball for old-school cred. The peripherals are modeled after the 8-Bit version of Super Mario Brothers, hence their truly retro, pixeled look. Bring one to work to show you’re a hardcore retro gamer…and proud of it. And we mean that in the best possible way. Available for $25 USD.
