Slice the cantaloupe and use the melon baller to scoop it into balls.
Arrange the cantaloupe balls on a serving platter.
Place the flat side down so they don't roll around.
Top with the blackberries.
Decorate with plastic spiders.
Serve.
Notes
Store leftovers in the fridge in an airtight container and enjoy within one day. You can also freeze them in a single layer to use within three months.
To make the plate even more festive, top the fruit with candy eyes and plastic spiders.
If you don't have a melon baller, simply cube the melon into similar chunks.
