Kamen Rider Den-O + Shin-O

When Misae is trying to get Shin-chan ready for the bus on time, he suddenly has to go to the toilet. As Misae pleads to him to hold it in until he gets to school, Shin-chan manages to get inside, but instead of the toilet he finds himself on the DenLiner and on Ryotaro's face. He quickly becomes smitten with Hana and Naomi, much to their chagrin, while everyone tries to figure out why Shin-chan has managed to get on the DenLiner. Back in the Nohara house, Misae bangs on the door as the Fatass Imagin tries to grant Misae's wish, which is to get Shin-chan to the bus on time.
