Spelling: Rice Krispies. Some of these things I’ll let slide, but do we have to spell stuff weird for brand names? Crisp starts with a “C.” What’s a krispy? I assume that’s the singular form. Wikipedia actually has an entry on this concept.
Another point might be copyright/trademark/whatever protection.
You can't get a generic name protected for the item it describes.
If you want to sell apples, you can't get the name "apples" protected for them.
(in contrast to e.g. computers)
So you need to use a more unique name. At best one, which is easily recognizable. So you might go with... err... abbles for your apples.
(or just with something totally different)
