How to Get Yoshi to the Island (Shortcut)/島の土管に早道
This makes the trip across the boats a bit faster but it's much more difficult to learn.
When you enter the sewer, push and hold "forward", keeping it pushed until you start to do Yoshi's spin (rotate the control stick). You should start your spin just before the apex of your jump. As soon as Yoshi starts his spin press and hold "A" as well as "forward" until you land on the platform. Continue to practice and it will become very easy.
