I can prove you wrong, SpaghettiOs is an American brand of canned ring-shaped pasta pieces in tomato sauce. It is marketed to parents as "less messy" than regular spaghetti. More than 150 million cans of SpaghettiOs are sold each year. They are sold in tomato sauce and with additions including meatballs, pieces of processed meat resembling hot dog slices, beef-filled ravioli, and calcium-fortified spaghetti.
While SpaghettiOs is a trade name, the equivalent food made by various manufacturers is available in many countries as 'spaghetti hoops', 'spaghetti loops', or 'spaghetti rings'.
