It's cute to see such a simple dance that's easier for little kids to learn again.
Episode 3 adds the traffic safety rules! The fight for traffic safety continues!
I caught episode 3 with a friend and he pointed out what might be a reference to an old Hirai Ken song! When Tokeiguruma goes down he says, 'Now the clock can't move anymore' (sub translations may vary) but the line in Japanese is 'Ima wa mou ugokanai.. sono tokei' which may come straight from Oukina Furudokei (Big Grandfather Clock). I had completely forgot about being a Hirai Ken fan until he mentioned it since I was into him 20 years ago lol. I have since re-added his songs to my Jpop playlist and what a blast from the past.
