OK, I've noticed while running Odyssey that when I enter one of the rooms in snow kingdom to get a moon or two (bloey-joey room, Rango room and goomba room) that sometimes a short, half second cutscene, will play of Mario walking in. But SOMETIMES it doesn't and allows you to roll right away, saving about a second and a half in total. Is this something that can be manipulated, or is just by chance like fast action guide skip? I've never heard any of the top runners talk about it...

that'd be good! because sub hour might be possible (cause lilkirbs got 1:00:00, so if he'd be on the same pace but use that he'd potentially get 59:58.500)

It only displays the cutscene, the first time you enter one of the 4 rooms. When you die in one of the rooms, it automaticly allows you to (for example) roll right away.
