Angie - I know what you're talking about now!! They're not Caraway seeds, but Fennel Seeds!!! They do look identical to Caraway, except are frequently paler or more greenish in color; but while Caraway is used primarily in baking (like rye bread), in sauerkraut, & many German & Danish dishes, Fennel Seed is most frequently used on pizza, in Italian sausage, poultry, etc. I've never seen Caraway on pizza, but have often seen Fennel seeds on it.
And yes, they do look like tiny little watermelons - lol!!
