yoshi fun

You get yoshi and put him on the missing slot on the yoshi go round then do a level without fludd and finish it,and grab shine and your done.

But yoshi must be orange.

In the park area, the Yoshi egg is behind/left of the Pianta tree. Feed Yoshi the pear hanging from the nose of the Pianta tree, or the pineapple under the purple gazebo, to turn it orange.
Stand on the Yoshi-Go-Round, where the orange Yoshi is missing, to get into the secret level.

Jump/bounce/hop across the rotating blocks in front. From the upper left corner of this platform, jump to red yoshi block and jump quickly across to blue yoshi blocks in the middle (notice that the green and blue yoshi blocks move faster than the red and black ones). On the other side, cross in a similar fashion.
Jump to orange block that will take you to the orange block area. Go left, then up and jump on moving orange block moving in L-pattern. Jump right. Backflip up block. Face tower of orange blocks head-on with Y, then jump wall-to-wall with A and joystick. At top, jump across to 3 orange blocks. Jump onto orange block that is rising/falling. Jump off it when it is at it's highest point to next orange blocks, then jump towards Shine Sprite.
If you're wondering about those 3 blocks: ice block melts with water, brick block gives 1UP mushroom, watermelon block gives 1 coin.
