I have had my fair share of Lucky charms and they have always looked like this:


Notice there isn't tons of frosting on the cereal. OP's picture I assume is a mix of cereals to make it look as sugary as possible in an anti-sugar message. I believe this because 1) not the right shapes 2) way too much frosting 3) sprinkles.

The rainbow unicorn shape is from a fairly new lucky charms release but i have never seen that include that much frosting or sprinkles.
