On the website for the "Doraemon: New Nobita's Great Demon / Peko and the Exploration Party of Five" movie you can play a simple little quiz to win a papercraft Doraemon explorer's hat to download!
Even if you don't speak Japanese, you can guess the answers with a little trial-and-error (or you can look at the bottom of this post... ;o)
After ticking the answers, click the brown "採点する" button at the bottom and when you get a score of "100", scroll down again but now you can click a new, red "「映画名場面カード」ゼント" button which will take you to a new webpage where you can click the green "ダウンロード pdf" button at the top to download the PDF file.
