Mega Man No Damage Runs 9: Dive Man

Dive Man is my favourite aquatic Robot Master and his level is pretty fun. It requires a lot of fancy footwork to navigate the spikes and stingrays. I used the Flash Stopper to freeze the whale minibosses; I probably could have used the Mega Buster, but it's pretty much luck whether you get hit by their weapons, so I went the cheap way. I attempted to destroy Dive Man with the Mega Buster, but I could never do it consistently, so I gave up and used his weakness, the Skull Barrier.
UPDATE 03-01-20: Beating Dive Man with the Buster is far easier than using the Skull Barrier. I have no idea how inept I could be to not do that!
