Cut a round cross-section from the centre of the melon about 15 cm (6 in) in diameter for the skull. Use a small round cookie cutter or knife to cut two eye-socket circles from the round, then fill the holes with blueberries. Place the skull at the top centre of the board.
Below the skull, lay five to six banana rounds in two curving parallel rows to form the ribcage shape, leaving a narrow gap between the left and right sides.
Arrange a cluster of green grapes in an oval shape below the ribcage to represent the pelvis.
For the spine, lay a single column of kiwi ovals between the ribcage rows and continuing into the pelvis area.
Build the arm bones: line orange segments end to end outward from the shoulder area (top of the ribcage), bending slightly at the elbow point. Use strawberry halves at the shoulder and elbow joints.
Build the leg bones: continue orange segments downward from the pelvis, bending at the knee. Add kiwi slices as the lower leg and three small strawberry pieces as the feet and toes.
Brush banana and kiwi pieces with lemon juice to prevent browning. Serve within 2 hours.
