Buzzblob

Buzzblobs are recurring enemies in the Legend of Zelda series. Mobile creatures made of goo, Buzzblobs are passive, but generate large amounts of static electricity. Although this could be both a defense mechanism as well as a weapon with which to stun its potential prey, the former seems more likely. These can typically not be defeated by swords, requiring the use of various ranged weapons. Typically, they are found exclusively in a game's respective overworld. A mainstay in 2-dimensional games in the series, Buzzblobs are known for transforming if a specific item is used on them. Buzzblobs may be a forerunner to the ChuChus appearing in later games in the series.

The Legend of Zelda: A Link to the Past
Buzzblobs cannot be defeated with any sword except the Golden Sword. If this is attempted, Link is shocked and stunned temporarily. If Link sprinkles Magic Powder on one, it transforms into a Cukeman, and spouts inane gibberish when spoken too. They can still shock Link in this state. They can be defeated with ranged weapons such as the Boomerang, Magical Boomerang, Bow, and Hookshot as well as the three magical Bombos, Ether and Quake medallions.

The Legend of Zelda: Link's Awakening
A small number Buzzblobs are found on Koholint Island. If Link sprinkles Magic Powder on them, they transform and speak in riddles when spoken to. The Boomerang, Bow, Hookshot and Magic Rod can all be used against Buzzblobs. The Giant Buzzblob serves as one of the mini-bosses of the Color Dungeon, a bonus dungeon only featured in the Game Boy Color version.

The Legend of Zelda: Oracle of Ages & Oracle of Seasons
Buzzblobs are more common than in Link's Awakening, but retain the same attack pattern and design. If Link uses a Mystery Seed on one, it transforms and speaks gibberish. The boss of the dungeon with the magic boomerang is a giant blue Buzzblob with piranha plant heads. To beat it, Link must throw the boomerang and make it hit any head. Eventually, the heads will fall off and then the buzzblob can be beaten by throwing the boomerang constantly.
