It's Bulma's birthday and Goku is on his way from Mount Paozu to West City for her party! Heading out of the mountains he runs into some trouble with a tiger, but after some persuasion he gets the tiger to give him some directions (only Goku would leave to the city without actually knowing where he's going). Goku leaves the tiger in a predicament (hanging over a canyon), and proceeds to leap into the ocean, swimming his way towards Bulma's house. Meanwhile, already in West City, Krillin and Kame-sennin are also having trouble making their way to Capsule Corp. They duck into an alley to check their directions, and as they're debating which way to go, a young boy playing with a remote control car can almost gets hit by a truck! The truck driver curses out the kid and a policewoman runs over to see that everybody's all right. The policewoman explains to the boy that you should always look left and right before entering onto the street, and judging by the skid marks left behind the truck, she also scolds the driver for speeding. Seeing this as a perfect opportunity, Krillin asks the officer how to get to Bulma's house.
At Capsule Corp., Oolong is preparing the food as Bulma sits at the kitchen table and dictates to him what he should be doing. Just as they begin to get into a tiff, the doorbell rings as Yamcha and Puar have arrived. Meanwhile, Goku has finally gotten out of the ocean and is now running through the farmlands and into the outskirts of the city. He arrives at a major highway and sees Snow trying to hitch a ride on the other side of the road. Goku tries asking if he's arrived in West City yet, but Snow is having trouble hearing him, so Goku just goes ahead and runs across the highway almost causing a major accident. The horrified Snow explains to him that you should always check left and right before crossing the road, and only cross busy streets at crosswalks. Goku doesn't seem very interested and reiterates that he's looking for West City, and Snow tells him that she's also headed to West City.
Back at Capsule Corp., Krillin and Kame-sennin arrive and find that Yamcha has also been recruited into cooking. Meanwhile, Goku and Snow begin walking through the fields towards the city, as Snow explains that she's meeting with her relatives, and Goku explains that he's attending a birthday party. Snow realizes that Goku doesn't even have a gift for his friend, so once they get into the city Snow tries directing Goku to a department store. Completely ignoring what Snow had taught him about traffic safety, Goku runs right out into the street again, almost getting hit by a car. The policewoman from earlier sees all this and comes over to explain that you can only cross in the city when the walk signals are blue. Goku begins to cross, but the officer stops him again, explaining that once the light begins to flash it means that it's about to turn red and you shouldn't start to cross. Goku is still uninterested, but the officer explains that the rules must be obeyed for everybody's safety. Goku finally seems to understand!
Back at Capsule Corp., everybody's getting upset as they're waiting for Goku to arrive before they start eating dinner. Meanwhile, back in the city, Snow spots the people she was meeting and the young boy from their group runs across the street to greet her. As he's running across the street he is about to get hit by a car, but Goku manages to save him with the Nyoibo. Once again the policewoman shows up, and Goku asks her how to get to Bulma's house. Finally arriving at Bulma's house, Goku is stuffing his face much to the dismay of everybody else. Goku tries to lighten the mood by asking if they know all the traffic rules, which sets everybody off into a big brawl! Goku and Kame-sennin address us directly (talking to the screen), and make sure that we understand the importance of the traffic rules. They then all chase Goku into the street and the Policewoman blows her whistle and everyone salutes! The traffic safety parody of "Makafushigi Adventure" then begins to play!
