quote Insanity Prevails

Q4: There's an island with a pipe that is covered with orange slime. I know that
only Yoshi can remove the slime but how do I get Yoshi there?
A4: Tough one this. Get Yoshi and head to the area near the shine gate. A boat
circles round here so jump on when it nears (make sure to keep Yoshi's juice meter
as full as you can while you wait). When it nears one island jump to it and eat the
fruits off the tree there. When the second boat comes near jump to it and ride it to
a small platform. Jump onto it and eat the fruit. Then ride the third and final boat
to the island. Make sure Yoshi doesn't touch the water at any time. In the pipe is a
secret red-coin level. Tip: if you miss a coin DO NOT EXIT! You'll have to get Yoshi
there again. Simply kill Mario to retry the secret stage.
