Paper Mode: Press and hold R to make Mario turn sideways. If you use the control stick to make Mario walk in this mode, he can fit through narrow spaces.

Rolling Paper Mode: Hold down R and rotate the control stick to roll up into a tube. Then Mario can roll under obstacles or into low, small spaces.
Paper Boat Mode: Find a boat platform and press and hold R. You will turn into a paper sailboat that you can control. To turn back into Mario find the same or a different boat platform and press and hold R.
