Librari

Librari is the elder of the Town Minish in The Minish Cap. He lives in Hyrule Town's library and is the twin brother of the Forest Minish elder, Gentari.

The Minish who lives near the Temple of Droplets says that Librari used flippers to travel into the temple. Link then speaks to Librari and falls down a hole where the flippers are hidden, and after maneuvering in the small dungeon runs into the flippers which allow him to swim and dive.

Librari's name is probably a reference to the word Library, also the place in which he lives.

Manga
In The Minish Cap manga, Librari tells his feather comes from a cucco he defeated when he was younger. He also hides a magic feather in the map he gives to Link; that feather transforms into a Roc's Cape during Link's battle against the Gyorg Pair.
