The Giant Buzz Blobis a mini-boss of the Color Dungeon in Link's Awakening DX. 
This boss is comparable to a regular Buzz Blob but is much larger and more formidable, and blue instead of green. Upon his defeat, the door to the Nightmare Key will open.
To defeat the Giant Buzz Blob, Link must sprinkle Magic Powder upon him. Once done, he must be struck with the sword. Throughout the battle, Giant Buzz Blob will shoot lightning bolts which the young hero must avoid.
