Find Mii (StreetPass Mii Plaza)

Find Mii (called StreetPass Quest outside of North America) is one of fourteen sub-games in StreetPass Mii Plaza, and one of two games alongside Puzzle Swap that is initially accessible to the player. This sub-game is a role-playing game in which the player can recruit heroes with Play Coins. By playing Find Mii, the player is able to earn hats that the Miis in their plaza can then wear. Certain hats can only be unlocked on the second playthrough of the sub-game. Completing Find Mii twice unlocks Find Mii II.

Story
In Find Mii, the player's Mii is the ruler of their own kingdom. Just as they settle into a royal slumber, they are kidnapped by a group of ghosts and brought to the Ultimate Ghost at the top of the Mirage Tower. In order to restore peace to the kingdom, troops of warriors are required to pass through difficult terrain, where they encounter various types of hostile ghosts. Throughout this journey, the player's Mii will provide useful hints regarding how to bypass certain difficult obstacles.

Upon reaching the summit of Mirage Tower, the heroes must contend with a powerful armored fiend who guards the cage in which the player's Mii is trapped. When the boss is defeated, the cage is lowered and the bottom opens up, temporarily freeing the player's Mii. However, just as the Mii rejoices in their newfound freedom, the Ultimate Ghost grabs them, prompting a more difficult final battle and causing the first hero in line to flee from fright.

Once the Ultimate Ghost is finally defeated, he will dissolve, allowing the player's Mii to roam free once and for all. The player's Mii thanks the heroes and commends their courage before waving at the player, thus ending the sub-game.

Recruiting heroes
In Find Mii, a level 1–2 wandering hero can be recruited with 2 Play Coins. These heroes take the form of anthropomorphic dogs or cats, depending on what the player has set their preference to in StreetPass Mii Plaza. Up to 10 heroes can be recruited at once, so it is necessary to recruit multiple squadrons of heroes in order to complete the sub-game. The player can also recruit as many as three Miis from their plaza at a time. Miis can be anywhere from level 1 to level 7; this number directly corresponds with the number of StreetPass interactions the player has had with a given Mii. The higher a hero's level, the more damage they are able to deal with both melee and magic attacks. However, higher-level Miis are also more expensive to recruit.

Combat
Once a group of heroes has been recruited, they will travel room by room to defeat the enemies found within. Though the foes in Find Mii do not get the opportunity to attack, each hero can only attack once before being scared off or having to retreat from fatigue. Therefore, the more Miis or wandering heroes the player recruits, the fewer attempts are needed to bypass each room.

Only one hero can attack at a time in Find Mii. Heroes have three combat options in this sub-game, as listed below.
 * Attack: A hero will attack with their sword, dealing a mild amount of damage to one enemy. This option allows for the possibility of a hero receiving an extra strike, or even landing a critical hit to deal more damage.
 * Magic: A hero will cast a particular spell depending on the color of their shirt. The effects of magic apply to all enemies.
 * Return: A hero will return to the back of the line, giving their turn to the next hero in line.

Some enemies in Find Mii are immune to certain types of magic, while others carry shields that protect against melee attacks but break if a certain-colored Mii strikes them. Enemies' strengths and weaknesses are important considerations in the completion of this sub-game.
