|“||This huge mariner shoots a huge cannon. Steal his huge shots and return huge fire!”|
|— Blast Mariner's Cast Description • Kirby's Epic Yarn|
Blast Mariner appears exactly like a regular Cannon Mariner except much larger, and with two shades of blue in his eye instead of one.
Blast Mariner only has one form of attack and that is shooting missiles from his cannon on his head. He will normally shoot three at a time. Kirby and Prince Fluff can throw these back at the Blast Mariner. Occasionally, the Blast Mariner will shoot one giant missile which cannot be wrapped up and can also shoot five missiles at a time.
In order to defeat the Blast Mariner, Kirby and Prince Fluff must throw his missiles back at him three times. He will explode and give the duo many beads.
