I don't go by the cereal section of the grocery store all that often (I don't like eating cereal in the morning - Probably because I don't like putting milk in it), but I haven't seen either of these Sesame cereals here in Canada. I'm actually a little curious now.
Speaking of character-based cereal, does anyone remember Winnie the Pooh's Hunny B's? Now, THAT was a yummy cereal!
