Dudim Phreykunoutonthis is an enemy class in Super Mario World 2: Yoshi's Island and its reissue, Yoshi's Island: Super Mario Advance 3. Its name is a pseudo-scientific corruption of the phrase "Dude, I'm freaking out on this," referring to the disorientation and dizziness a Yoshi experiences whenever it comes into contact with or swallows a Fuzzy, the only member of this class.
