Dragon Ball: Yo! Son Goku and His Friends Return!! is a 35-minute Japanese animated short film based on Akira Toriyama's Dragon Ball series, shown on the Jump Super Anime Tour from September 21 to November 23, 2008. It was the first animated Dragon Ball film in twelve years, following the tenth anniversary film The Path to Power.
Two years after Majin Buu's defeat by Goku, Mr. Satan, feeling guilty that his new hotel is in honor of what the majority of Earth believes to be his victory over Buu, invites Goku, Vegeta, and their families to a banquet. During dinner, two Saiyan spaceships land and a mysterious Saiyan and his wife confront the heroes at the hotel. Vegeta's younger brother, Tarble, introduces himself and explains that he was deemed weak by their father and sent to a distant planet before the destruction of Planet Vegeta. He also introduces his wife Gure, a small alien humanoid. Tarble asks his brother for help in dealing with Abo and Kado, soldiers from remnants of Frieza's army, who are causing havoc on his planet.
As Abo and Kado arrive on Earth, the heroes pick radishes from Goku's garden to determine who will battle the duo and Goten picks the longest. Pressured by his father, Trunks picks out a radish that stretches for miles. Goten joins Trunks in the fight and the children easily defeat the two soldiers until Abo and Kado create doubles of themselves. With encouragement from Gohan, Goten and Trunks gain the upper hand. Abo and Kado merge into their larger, more powerful form, Aka.
Aka devastates Goten and Trunks so they perform the Fusion Dance, fail their first attempt, but succeed with in the second. Now fully powered as Gotenks, he quickly appears to defeat Aka. However, while everyone is celebrating, Aka attacks again after Gotenks taunts him; but Piccolo blocks the attack. Aka destroys most of the hotel and with the threat growing, Goku and Vegeta join the fight; but Goku tricks Vegeta into looking away while he defeats Aka with a Kamehameha wave. With the battle over, everyone returns to what is left of the hotel and continue the banquet. Abo and Kado join in on the feast. The special ends with Goku and Vegeta fighting over food, transforming into Super Saiyans as they argue.
