Question: Monster cereals, are monster-themed breakfast cereals, collectively called the monster cereals, are five current, and formerly distributed, breakfast cereal brands in North America, by which American multinational manufacturer and marketer of branded consumer foods sold through retail stores?
Context: This is a list of breakfast cereals.  Many cereals are trademarked brands of large companies, such as Kellogg's, General Mills, Malt-O-Meal, Nestlé, Quaker Oats and Post Foods, but similar equivalent products are often sold by other manufacturers and as store brands. Morning Funnies is a fruit-flavored breakfast cereal produced by Ralston Cereals in 1988 and 1989.  The name of the cereal was based on the assortment of newspaper comic strips featured on the box.  Innovative packaging allowed the back flap of the box to be opened revealing additional comic strips, different on each edition of the cereal box.  Poor sales and negative consumer reaction led to the cereal being discontinued in 1989. Farina is a form of milled wheat most often used to prepare hot cereal for breakfast.  The word "farina" is Latin, meaning meal or flour.  It is made from the germ and endosperm of the grain, which is milled to a fine granular consistency and then sifted.  This results in a carbohydrate-rich food.  When enriched, it is one of the best sources of dietary iron available, especially for vegetarian diets, with most brands offering as much as 50% of the recommended daily value in a single 120-calorie serving.  For commercial cereals the bran and most of the germ are removed and is sometimes enriched with Vitamin B and iron.  Cream of Wheat, Malt-O-Meal, and Farina Mills are popular brand names of breakfast cereal.  Due to its mild taste, the cereal is often flavored with brown sugar, maple, honey, nuts, cinnamon, butter, grated chocolate, jams, salt, fruits and combinations and variations of these items. Ripple Crisp was a breakfast cereal produced by General Mills.  It was introduced in 1993, and consisted of corn flakes made with horizontal ridges.  According to the marketing, the ridges were designed to "keep out the milk and lock in the flavor for a crisp, delicious taste in milk", while traditional flake cereals "were flat.  Milk just sat on them, making them soggy."  Ripple Crisp was promoted with the slogan "The Shape Of Flakes To Come!"  The cereal came in two flavors, "Golden Corn" and "Honey Bran".  A collection of consumer reviews from Deseret News summarized the cereal as being "tall on crunch, short on taste".  General Mills' official Twitter account recognized the cereal in a 2013 tweet. General Mills Corporation's monster-themed breakfast cereals, collectively called the monster cereals, are five current, and formerly distributed, breakfast cereal brands in North America.  The series includes Count Chocula, Franken Berry and Boo-Berry, in addition to the long-discontinued, but temporarily resurrected, Fruit Brute and Fruity Yummy Mummy. Halfsies was a breakfast cereal manufactured by Quaker Oats from 1979 through 1984.  It was the result of the so-called "sugar backlash" in which the amount of sugar in children's breakfast cereals became an issue.  The premise was it contained half the sugar of regular breakfast cereals, and that it was half-corn and half-rice.  The cereal nuggets were shaped as half a normal cereal ring, like the letter C. Fruity Pebbles, Ice Cream Pebbles, and Cocoa Pebbles are brands of breakfast cereal introduced by Post Foods in 1971 featuring characters from the animated series "The Flintstones" as spokestoons.  The cereals debuted in 1971.  Cocoa Pebbles contains chocolate-flavored crisp rice cereal bits, while Fruity Pebbles contains crisp rice cereal bits that come in a variety of fruit flavors with a sugar content of 9 grams per serving for Fruity Pebbles and 10 grams per serving for Cocoa Pebbles.  It is the oldest cereal brand based on characters from a TV series or movie.

Breakfast cereal (or just cereal) is a food product made from processed grains that is often eaten as the first meal of the day.  It can sometimes be mixed with milk, yogurt, or fruit.  Some companies promote their products for the health benefits from eating oat-based and high-fiber cereals.  In America, cereals are often fortified with vitamins but can also lack many of the vitamins needed for a hearty breakfast.  A significant proportion of cereals are made with high sugar content.  Many breakfast cereals are produced via extrusion. Hubbard Foods Ltd is a New Zealand manufacturer of breakfast cereals based in Auckland.
