Shantae and the Pirate's Curse/Scuttle Town

Boss: Ammo Baron
Ammo Baron rides a large tank and will alternate between ramming with the tank or shooting cannonballs. Both attacks can be avoided by standing in front of the wooden crates. If you stand on the crates, you may get hit by the black cannonballs. Use the hair whip attack to knock back the bouncing red cannonballs. Ammo Baron will fall out of the tank and be momentarily vulnerable to attacks. Afterwards, he will get back in the tank and resume the attack pattern. Repeat attacking him when vulnerable to defeat him.
