Brand X cereal is a fictional competitor of Chex. It lacks nutritional value and taste. It is very popular (or tries to be) with the flemoids.
Their cereal is so bad that the best slogan they could think of is "It's almost as good as Chex®!"
It is high in vitamin Q, an unknown flemoid vitamin.
Ads and billboards for this cereal can be found throughout Flemtopolis.
