Furnix

Furnixes are phoenix-like enemies that appear in Skyward Sword in the Ancient Cistern.

Characteristics and Weaknesses
If they spot Link, Furnixes will spit three fire balls at the young hero. Right before they attack, they uncurl their tails, which can be grabbed with the Whip, causing them to plummet to the ground, making them vulnerable. It takes only three strikes from a sword to defeat these enemies.

Trivia

 * Their name is likely a portmanteau of "furnace" and "phoenix", the latter of which they bear many traits to, particularly their association with fire.
