Transformers cereal promos didn't end with Generation 1. The Transformers RID (2015) series worked out a deal with Nestlé to offer these cool little "Cyber Eyes" premiums.
Purchasing any of the large (330g / 300g) packages of Koko Krunch, Honey Stars, and Milo Cereals offered a random shot at one of the Optimus Prime, Bumblebee, or Grimlock figures with a special light-piping feature that makes the eyes shine brightly. Sadly, you've probably noticed these are not American cereals we know, and these little guys were only available in parts of Europe and Asia.
They're so cute, but those expressions! Light up eyes of SHAME.
