Original title : ケロッグ ワクワクドキドキ人気 ゲームキャラ大集合![ドキドキ賞]
From what I've figured out, a trading card was included in every Kellogg's corn flakes box, with a random hero from Konami, Namco or Capcom games. Sometimes, if you were lucky enough, you could get a special card that you had to send back to Kellogg's Japan in order to win a special demo.
There exist 2 different demo compilations (Dokidoki and Wakuwaku versions), Dokidoki being the rarest.
- Mister Driller demo + illustrations
- Dotsubochan demo
- Reverse Attack (an original game made by Kellogg's!)
- Kellogg's original CM compilation
