I can't find out how in the world you get Yoshi !!! HELP!!!?

Beat Pinna Park:Story four.

After you have done so there should be a cutscene of Shadow Mario standing in Delfino Plaza holding a Yoshi egg.

Do the usual chase him around and spray him until he gives up.

Then he should drop the Yoshi egg and disappear.

Bring the Yoshi egg the fruit it's thinking of and then it will hatch and you can ride Yoshi.

After you beat pinna park episode4 in episode4 turtles are atacking the sun flowers spray them with water and use ground pound on it do not touch the five turtles.

They are electeric once you defeat the turtles you get a shinesprite andget the coins that come out of the turtles once you beat episode4, shadow mario will leave an egg on the buliding on the left of ricco harbour theres an egg.

Go near the egg, whatever fruit you see get the fruit and bring it to the egg the egg will hatch and
jump on Yoshi, thats how you get yoshi.

P.S..once you give yoshi the fruit use b to eat different fruits and yoshi will change color.
