Cut watermelon in half lengthwise.  Using a melon ball maker, make balls from all melons.  Keep watermelon in 2 halves.  If you don't have a melon ball maker, just cut melons into bite sized chunks.  Scrape out one of the watermelon halves well.  Scallop the edges.  Rinse off rest of fruit and mix all fruit in large container.  Serve in melon half.
