Nackle is a character from The Legend of Zelda: Skyward Sword. He is a Mogma living at Eldin Volcano.
Etymology[]
As many Mogmas seem to be named after metals and other minerals, it is possible that Nackle's name is derived from nickel. Alternatively, it may be derived from nahcolite. It could also be derived from saying the chemical symbol of Sodium Chloride, NaCl phonetically.
