Weetos is a brand of chocolate-flavoured breakfast cereal produced by Weetabix Food Company. The name comes from the fact that its primary ingredient is wheat (Weet-) and the cereal pieces are in O shapes (-Os), the same naming convention that is used on the company's flagship cereal Weetabix (Wheat Biscuits). The brand initially began with the Weetos cereal, officially known as Weetos Chocolate Flavour, and has expanded to include Weetos Meteors, Weetos Bars (which are cereal snacks in bar-form), and Weetos Vs. Alien Invasion.
