Mr. AR
A bizarre little box creature, used as the somewhat in the background mascot of one of the 3DS' premiere features, the ability to display AR content. Using a selection of cards packaged free alongisde every early-era system, players were able to hold them to their 3DS camera and see detailed 3D models of everything from Mario, their own Mii, and even a dragon covered in weird targets. This little yellow box would often cameo between the transitions of the games available in the software, as well as appearing on the software's home-screen banner. Unfortunately AR on the 3DS saw very scarce use outside of this game (except for its excellent use in Tomodachi Life), leading to later 3DS models abandoning the pack-in cards entirely. Nevertheless, since 'AR Games' came preinstalled on every system regardless, it's very likely that almost every 3DS user has seen this little yellow box at some point during their time with the system.
