Never mind, I finally beat Toad. All you have to do is move at max speed except when you are in the inner middle part. When the white smoke comes out, then quickly move the control stick back and forth.
Anyways, After trying out some techniques, I've became a decent button masher, but I'll not beating mecha marathon from the mini-game coaster anytime soon. I really hate button mashers, they are lazy coding, bad for the controller, and straining on the hand.
