I like General Mills monster cereals Frankenberry, Boo Berry, & Count Chocula but I seen on a site that there was a Fruit Brute & a Yummy Mummy Cereal but I have no memory of ever seeing these cereals on the shelves. Why was these cereals discontinued and did you get to try them?

I never tried to get them. Fruit Brute and Yummy Mummy were not popular sellers so they were discontinued.

Frankenberry, Boo berry and Count Chocula are still being made but only in limited quantities. You can usually find them around Halloween time. You can still order by calling 1-800- 249-0562.
They can send you an order form and you can order direct from General Mills.

Fruit Brute was made in 1973 and was discontinued in 1983. (sales were really low)

Yummy Mummy was made in 1987. (I'm not sure when it was discontinued)

This link will show you some of the old cereals.

I bet they were great cereals. It seems like everything good becomes discontinued.
