Instructions
Use the "Boomerang Cutter" weapon as soon as the fight begins to cut off two of Launch Octopus's arms, severely limiting his attacks.
Use the "Rolling Shield" weapon if you have beaten the Armored Armadillo level prior to fighting Launch Octopus. Rolling Shield is Launch Octopus's weakness and removes almost a quarter of his energy bar with each hit. If you do not have Rolling Shield, use your standard blaster against him.
Dash under Launch Octopus when he jumps over you. If he comes into contact with you, you'll lose a small amount of health.
Shoot the torpedoes Launch Octopus fires at you. The torpedoes take one shot from your blaster for each one, and Launch Octopus shoots the torpedoes in groups of three.
Continue to destroy or avoid Launch Octopus's attacks, shooting him with your blaster whenever possible. Launch Octopus is defeated when his life bar, located on the right side of the screen, is depleted.
