Instructions for the Carrot Ghosts:
Cut a 7-8 cm (3 inches) piece of carrot and then slice it.
Using a knife, curve the top and zig-zag the bottom of each slice.
Use a metal straw for the eyes and mouth.
Instructions for the Clementine Pumpkins:
Peel the clementines.
Add a little piece of basil stems on top of the clementines to resemble a pumpkin.
Instructions for the Spooky Eyes:
Melt the dark chocolate.
Place the melted chocolate in a little bowl.
Dip the top of the grapes into the chocolate.
Top with a candy eye and allow to set.
Instructions for the Red and Yellow Pepper Ghosts:
Stick on candy eyes using some edible glue.
Add a mouth with a metal straw dipped in melted dark chocolate.
Instructions for the Kiwi Frankensteins:
Halve the kiwi lengthwise.
Cut a line across the top third of the kiwi.
Use a peeler to remove the skin underneath the line.
Dry the kiwi with a piece of kitchen towel.
Top with candy eyes.
Make the scar and mouth details with melted chocolate and a toothpick.
Stick pretzel stick ends into the side of the Frankensteins.
Instructions for the Strawberry Monster Teeth:
Remove the leaves from the strawberries.
Dip a small spoon into melted dark chocolate and then onto the front of a strawberry so it resembles a mouth. Use chopped pieces of flaked almonds or white chocolate discs as teeth.
Allow to set.
Instructions for the Witch Pretzel Broomsticks:
Cut the cheese into little blocks. Mine were about 4 cm. x  2 cm. (1.5 inches x 0.8 inches).
Trim broom bristles into the bottom half of the block. I made two or three cuts across on both sides.
Use a metal straw at the top of the block to create a hole. The cheese should come out with the straw if you move it back and forth gently.
Insert the pretzel stick carefully into the hole.
Instructions for the Melon Tombstones:
Slice the cantaloupe.
Shape the tombstones by hand. You can use a glass for the curved top.
Dry off the melon with a piece of kitchen towel (this will ensure the dark chocolate will be set properly).
Add melted dark chocolate to a piping utensil / bag and shape the word 'RIP’.
Allow to set
Arrange the platter.
