Kip. 4: The Dragon Team, All Assembled! Son Goku has Returned!!

4

After ten days of training, Videl manages to master flight, finally giving Gohan and Goten the opportunity to resume their training for the tournament. On the day of the tournament, Gohan suggests to Vegeta, Goten, and Trunks that they don't use their Super Saiyan forms during the tournament to avoid hassle from the press. Arriving at the island where the tournament will take place, Gohan and the others are greeted by Goku, who the fortune teller Baba has granted 24 hours to stay on Earth, allowing him to meet Goten for the first time, while Piccolo destroys all the cameras in the area to keep Gohan's identity a secret. After the participating fighters register for the tournament, with Goten and Trunks forced to participate in the junior division, the preliminary rounds begin, where the fighters must hit a punching machine to rank their strength, with the Dragon Team effortlessly qualifying. (Source: Wikipedia)
