Zirro

Zirros, alternatively known as Bombers , are flying mushroom-like enemies that appear in The Legend of Zelda: A Link to the Past, The Legend of Zelda: Link's Awakening, and The Legend of Zelda: A Link Between Worlds. Zirros usually attack by launching projectiles at Link. Bombers have a brown stem with small feet and small, glowing eyes and move around somewhat erratically.

The Legend of Zelda: A Link to the Past
In The Legend of Zelda: A Link to the Past, Zirros have two color variants, green and indigo, both of whom only appear in the Dark World. They are found at the Ice Lake and near the Swamp Palace. If Link tries to slash his sword at a Zirro, it swiftly dodges the attack, although Link can strike them if he moves quickly enough. Both Zirro variants can be defeated with the Hookshot or from a Silver Arrow.

Indigo Zirros only attack by swooping into Link. With the Master Sword, Link can defeat a indigo Zirro by striking it twice, or instantly with the Tempered Sword or Golden Sword. Green Zirros are weaker than their indigo counterpart, because the Master Sword can defeat them with one hit. To compensate, green Zirros have the ability to spit seed bombs, which deal two hearts of damage to Link if hit.

The Legend of Zelda: Link's Awakening
In The Legend of Zelda: Link's Awakening, Bombers attack by randomly dropping bombs on the overworld, which is comparable to how Green Zirros spit seed bombs in The Legend of Zelda: A Link to the Past, though the blast radius is larger. Like their debut appearance, Bombers fly out the way if Link attempts a sword attack. If Link is quick enough, he can defeat Bomber by slashing it three times with his sword, or twice with the Koholint Sword. He can instantly defeat Bombers with the Boomerang, an arrow, or the Magic Rod. If Link sprinkles Magic Powder on a Bomber, it turns into a fairy. In The Legend of Zelda: Link's Awakening DX, they are red, while in the Ninendo Switch remake, they are green, resemble their model in The Legend of Zelda: A Link Between Worlds, and are capable of actually changing altitude due to the new 3D plane. They also visibly spit out the bombs rather than simply spawning them.

The Legend of Zelda: A Link Between Worlds
In The Legend of Zelda: A Link Between Worlds, green Zirros appear in Lorule in the counterparts to the places they appeared before. They act the same, though their seeds no longer violently explode. It is indicated by the Bird-Masked Man that they used to be birds, but were turned into monsters by the evil permeating Lorule. Blue Zirros with gray stems are found on the icy Death Mountain, and are capable of shooting snowballs that freeze Link.
