Shiver Star: HR-H/HR-E

Start in the middle of the factory arena. HR-H has four attacks.

When HR-H uses its rocket launcher, watch for shadows and inhale a rocket if you feel lucky.

To avoid HR-H's punch attack, fly high and shoot a rocket at its arm. Time your escape carefully, as you must spit the rocket so HR-H draws its arm over it and you can get away. This is not recommended for Boss Battles.

For HR-H's third attack, where it charges both arms to crush Kirby, float upwards and quickly move left or right as HR-H raises its arms. Land and inhale the two boulders that appear when HR-H smashes its arms down. Exhale these boulders at HR-H for two hits.

Watch HR-H's eye. If it quickly turns left, jump to avoid a fast laser stream on the ground.

Land six hits on HR-H to trigger its transformation into HR-E.

As HR-E, stay on the left side of the screen to avoid its scissors attack.

Dodge HR-E's four small rockets by observing their pattern. You can inhale one and jump to shoot it at HR-E.

When HR-E fires a big rocket, inhale its front part. Jump over the rocket when it charges again and shoot the front part at HR-E.

After HR-E loses half its energy, it will fly up. Wait in the middle of the arena. When HR-E is a few centimeters above your head, run left to make it crash down next to you.

Land six hits on HR-E to defeat it.
