What kind of gelatin does rice krispie have?

Rice Krispies cereal itself does not contain gelatin.

Gelatin is an animal-derived protein and is not used in the production of Rice Krispies.

However, some Rice Krispies treats or recipes may contain gelatin. For example, marshmallow treats often use gelatin as a binder to give them their gooey texture.

If you are concerned about gelatin in a specific Rice Krispies product, it's best to check the ingredient list on the packaging.
