Buzz Blobs are species found in The Legend of Zelda video game series. They appeared solely in the 2-D, birds eye view Zelda games, though it should be noted that the Chu Chu species in the cell-shaded Zelda games (and The Legend of Zelda: Minish Cap) look strikingly similar to the Buzz Blobs of the other games.
As its name implies, Buzz Blobs are capable of generating jolts of electricity as a defensive mechanism to shock their opponents, notably Link, whom act as a major threat to them. Because of this, they are not able to be defeated by a simple slash of the sword, as the electricity will travel from the sword, to the wielder's body, thus shocking them. However, there is a simple way to kill them, and that is to toss or shoot some sort of projectile towards them such as an arrow or a bomb, so that the electricity won't be able to shock you.
