Wash the mango and slice the flesh away from the seed on both sides.
Form the central bud by making a circular cut, with the carving knife and then rounding off the flesh in the center.
With the carving knife, cut eight pointed petals radiating from the center and then remove flesh from beneath them so that they stand out.
Make the second circle of petals in the same way, centering them between those of the first circle. When complete, gently separate the flower from the remaining flesh.
At the flower end of the rose-apples, make slices in a circle through the wall of the fruit and then carefully pull the flower seed and membrane out.
Use the stem ends to make flowers. With the tip of the carving knife, form four pointed petals, and then cut through the outer face of each petal to make another smaller petal inside it.
Make the centers of the flowers from red apple peel. Cut the apple peel into disks and insert in the center of the flowers.
Wash the pineapple, pat with a cloth to dry it, and cut off both ends.
Cut the pineapple in half lengthwise.
Cut a V-shaped groove down the center of the core.
To form the head and the top of the wings of the butterfly, make a cut angled toward the center from both borders of the core and then make a shallow curving slice from the skin on both sides.
Remove the flesh from the skin by making cuts at an angle of about 45 degrees from both borders and then connecting the two by making a curving cut.
Turn the pineapple with the curved side up. Cut a single groove down the center of the curved bottom and two parallel grooves down each of the flat sides.
Cut the pineapple into one centimeter thick slices.
Cut two shallow grooves down the center of the leaf which converge to the Lip of the leaf to represent the midrib. Cut notches in the edges of the leaf, working from base to tip.
Cut grooves branching from the midrib, again working from base to tip.
