In this game, you can get sort of strangely stuck against invisible walls. It can be done with the See the unfinished parts of Noki Bay glitch and it's necessary in the Get under Gelato Beach glitch. You jump and hover at the invisible wall and hold forward and you'll be floating against the wall, even without hovering. Then, Mario will make the falling scream and make the falling motions, though he won't be going anywhere. Changing the camera or moving the control stick may make him fall. This only happens with some invisible walls.
