Good point.  I think what we’re seeing here is that Google doesn’t quite know what chocolate cereals are.  But I can imagine that in a chocolate cereal company’s marketing literature, they’d say Fruity Pops is a chocolate cereal.

That’s true, it doesn’t have chocolate in the name.  Maybe you could ask Google for help on that.  (Just a note:  There is such a thing as “chocolatey chocolate” but it is pretty unusual, and if someone says “chocolatey chocolate”, it’s probably because they actually mean chocolatey flavors instead of actual chocolate.)

What are some good chocolate cereals?

Hmm, I don’t know!  But let’s see what Google and Wikipedia say about chocolate cereals.

I don't think Fruity Pops would be chocolatey
