Twins

The Twins are characters in The Legend of Zelda: Ocarina of Time and The Legend of Zelda: Majora's Mask. They are never officially named, but they appear to be twins. They are almost always seen together and they are identical in appearance, barring the different color clothing.

The Legend of Zelda: Ocarina of Time
In Ocarina of Time, the Twins reside in Hyrule Castle Town. They are mainly filler characters, but they do reveal a tip to Link that tells him the proper way to sneak into Hyrule Castle. They tell Link a story about how the Twin wearing blue clothing attempted to sneak into the Castle to meet Princess Zelda. He snuck past the Hylian Knights, swam through the moat, and tried to crawl through the drain hole on the side of the castle but he got stuck because he was too big. This story reveals that Link may be small enough to crawl through the drain hole and enter Hyrule Castle. The Twin in red then says, however, that they have tightened security at the castle due to the other Twin getting caught.

When Ganondorf takes over Hyrule, the Twins retreat to Kakariko Village, but they stay in different houses.

The Legend of Zelda: Majora's Mask
In Majora's Mask, the Twins are jugglers employed by the Gorman Troupe. They are visiting Clock Town to perform their act during the Carnival of Time. They spend their days practicing their juggling in East Clock Town, and at night they play cards in their room at the Stock Pot Inn together. The two are always cracking jokes, and overall seem to be very jolly fellows.
