Flying tiles have appeared in a handful of Legend of Zelda games, but in Echoes of Wisdom, you'll need one to complete the appropriately named "The Flying Tile" side quest. These "enemies" are exactly what they're stated to be: panels that lift off the floor and fly towards Zelda or Link. They don't normally deal much damage, but you'll want to block them before they can chip away at your character's health. There are two places that have flying tiles in Echoes of Wisdom, and they're all located in the Gerudo Desert.
