The special videos "Goku's Traffic Safety" and "Goku's Fire Fighting Regiment" are both very rare productions designed to be educational films. They were both completed in June of 1988.
In "Goku's Traffic Safety", Goku is heading to West City to attend Bulma's birthday party, and on the way he ends up learning the rules for getting through traffic. The movie was for children to watch so it would teach them how to get across a pedestrian crossing. Guest characters include an appearance from Lunch as a policewoman (she had the personality of Normal Lunch, but with the blonde hair), as well as Snow, who was first introduced during the Muscle Tower episodes. In 1 cut Namu appears as a passer-by going across at the pedestrian crossing, Oolong is helping cook with all his might, and you need to check out Yamcha in the frilly apron. For the ending, all the actors seem to be singing a traffic safety parody version of "Makafushigi Adventure!", although it's of pretty strange taste.
