About StreetPass
StreetPass is a feature for the Nintendo 3DS. WiFi must be enabled to use it. With both WiFi and StreetPass enabled on a 3DS, it will send and receive signals to other 3DS's with the same aforementioned requirements. This will allow one to communicate with the other via special applications on the 3DS, and sends their favorite Miis to each others' systems. From here, the owners can use the other person's Mii in games found in the 3DS Mii Plaza. StreetPass also gives the players a small amount of personal information about the other, such as what video games they've played recently, what their dreams for the future are, and if they're a "cat or dog person." StreetPass can only be successful if the two systems are very closeby; most preferably in the same building.

StreetPass was introduced in most of the first few 3DS games, and has since played a role in most major 3DS games. Most of the time, it only plays a role as unlockable bonuses in games (meeting new Miis being the way to unlock them,) whereas in games from the Mii Plaza, it is impossible to complete them without it. Although, the game does not have to be originally for the 3DS for StreetPass to work on it. Games bought in the Nintendo eShop, Virtual Console games, or even Nintendo DS games will appear as a Mii's "recently played" game.

StreetPass in Zelda games
StreetPass, as previously mentioned, will work in some small ways for all Zelda titles playable on the 3DS, even the two DS games, but only plays an important role in.

A Link Between Worlds
In, StreetPass allows the player to fight two extra bosses not available without it. Should the player speak to Gramps, located in the StreetPass Meadow in Kakariko Village, he explains to the player how StreetPass works. With the help of Gramps, the player can create their own personal Shadow Link that serves as a substitute to the player's favorite Mii. If a person playing Link Between Worlds StreetPasses someone else doing the same, their Shadow Links are sent to each others' games where they are fought as a kind of "secret" boss. The Shadow Links are customizable, with different gear depending on the player's choosing. Once the player's first Shadow Link is created, Gramps plants the StreetPass Tree next to Link's House. One apple grows on the Tree for each Shadow Link defeated by Link, and for each apple the player gains a Challenge Medal. After obtaining 50 Challenge Medals, Gramps challenges Link to a duel, where he fights as arguably the game's most difficult boss.
