Bring 1 cup of water to the boil in a small pot (if using).
Use a sharp knife to remove green leaves from strawberries. Remove ends and skin from kiwifruit. Cut off skin, cut in half lengthways and then in half again widthways. Use a tablespoon to scoop out 6 balls of melon.
Place chocolate in a heatproof bowl (larger than the top of your pot of boiling water). Place bowl on top of pot, reduce heat to low and stir until chocolate has melted.
Pour chocolate into a small piping bag with small nozzle attachment (or use a snaplock bag and cut a small hole in the corner). Set aside to cool for about 10 minutes.
While chocolate is cooling, thread fruit and marshmallows onto skewers and place on a clean board. Use the piping bag to draw some fun Halloween faces on, or get the kids to try their hand at doing their own!
