i remember trying to learn a super basic turnip combo a while back, and it took me hours. these look 10 times harder, and you have them mastered. literally godlike.
If ur talking about the footstool stuff its just: jump, jump+z (hold down to float), let go then press z again to re catch. There's no real secret, just good timing. I don't think it's possible without float unless ur doing zadc, which- that shit is impossible
Jump+Z drop at the same time. Hold down on control stick to get float drop. Z catch, wait til landing, turn around repeat. Hard to explain in text, so I'll make a tutorial soon
