A sixty minute special of the Crayon Shin-chan anime featuring a crossover between Shin-chan and the live action tokusatsu series Kamen Rider Den-O, as well as three normal summer-themed episodes. The Den-O characters are drawn in the style of Shin-chan's regular characters. Another thing of note, inbetween commercial breaks, clips of a live action Shin-Chan onboard the Den-Liner or with characters from the Kamen Rider Den-O Series were shown.
