Super Mario Galaxy 2: Infinite Yoshi Flutters
There is a glitch in Super Mario Galaxy 2 for the Wii where can use Yoshi’s flutter almost indefinitely.
All you have to do is jump and hold A to do his flutter. Before you finish fluttering, while still holding the A button quickly press the Z button, then let go of A and Z both, then press A again to flutter. Keep repeating this process and you should keep fluttering all you want.
