Does anyone here know a good way to not only get the strats down to fight broodal mech aka birdless +just staying on it after each hit but also in order to practice it do I have to keep a file save before I fight it in bowser kingdom? Its a really annoying boss fight and I do not seem to understand the strats

to keep a save file before you fight the boss, die before landing the final hit.

do the boss as normal then once you are about to win, die on purpose

I have a tutorial on Youtube. It doesn't do birdless, but it does go over timings for staying on and the boss' pattern.

Awesome can't thank you enough
