The great RNG boss. It's one of those bosses that theoretically can take an indefinite amount of
time to beat. In the first phase, there are four possible attacks: "slap", "clap", rockets,
When HR does one of the latter two attacks, it can't be damaged. During the other two attacks,
HR exposes his arms. The strategies for attacking are designed for fire sword (fire + cutter),
which can be picked up at the end of 5-4.
HR can be damaged during his "slap" attack (left video) simply by holding the sword out and
jumping over the outstretched hand. A simple strat for the "clap" shown in the middle can get
three hits on HR. It's possible to squeeze in four attacks into one clap with the strat in the
video on the right. There is a small space where Kirby can stand: too far to the left and the
sword doesn't hit the arm, and too far to the right causes Kirby to get hit. My visual cue is
to align the end of Kirby's left foot with the green and black part of the walkway. The video
doesn't show this, but I've found that getting the fourth hit is easier when you're higher
up (i.e. after doing a jump).
During the second phase, you can hold the fire sword vertically and hit HR's "nose."
After three hits, HR will fly up into the sky and try to drop on top of you. The goal is to
manipulate HR into the middle so he becomes vulnerable again sooner. Once he lands, do another
three hits to finish him off. It's possible to throw the double-powerup, but I don't think
it's worth it since it can hit one of its attacks instead.
In this phase, HR has three attacks: rockets, claws, and one big rocket. For rockets,
the attack probably won't hit you. The claws will attack in front of HR, so stand farther to
the right while still attacking. The big rocket, will get hit by the sword as long as Kirby
