Wash the apples, strawberries, grapes, and celery and dry thoroughly.
Peel the bananas and cut each one in half crosswise.
Press two mini chocolate chips into each banana for eyes and another for the mouth. Lightly brush exposed banana with lemon juice.
Peel the clementines while keeping each fruit intact.
Cut celery into small stem-shaped pieces and insert one into the top of each clementine.
Cut the apples into thick wedges and remove the cores. Lightly brush cut surfaces with lemon juice.
Spread peanut butter onto the inside surfaces of two apple wedges.
Arrange mini marshmallows between the wedges to create teeth.
Add a thin strawberry slice for a tongue and gently sandwich the apple wedges together.
Arrange 6–8 green grapes in a curved line for each caterpillar.
Attach candy eyes to the front grape with tiny dots of melted chocolate.
Melt white chocolate in 20-second microwave intervals, stirring between each interval.
Dip completely dry whole strawberries into the white chocolate.
Place on parchment paper, allowing a small chocolate trail to create a ghost-like shape.
Once partially set, add eyes and mouths with melted semi-sweet chocolate.
Allow strawberry ghosts to set completely.
Arrange all five Halloween fruit designs naturally on a large serving platter.
Refrigerate until serving if necessary and serve fresh.
