You could make your own Rice Krispy Treats, but if youre making only a few, its Zombie code to buy them premade.
1 box individually wrapped Rice Krispy Treats
1 small box Trix cereal (you can get the small 1 serving each 8 small box combo thing)
Separate colored cereal pieces and crush them. Reshape treats into egg shapes, dip into crumbles you want the egg to be, you can use more than one color to create patterns. Youre Done! Clean up is a matter of vaccuming.
