|"The Full Moon"|
|Arc||Hunt for the Dragon Balls Arc|
|Japanese||April 23, 1985|
As the Dragon Team attempts to break out of the steel prison, Emperor Pilaf and his gang head to bed. Pu'ar informs Oolong that he is staring at the full moon after the piglet asks of his actions, much to the piglet's disarray and confusion given the situation. After overhearing the phrase "full moon," Gokū tells of a story of a scary monster appearing during a full moon, which earns Gokū the scorn of Bulma. As Gokū claims this monster's appearance was the reason why his grandfather is dead, Yamcha and Oolong are in awe of the story, but Gokū claims he does not remember his grandfather's death due to being asleep.
When Gokū reveals that his grandfather told him to refrain from looking at the full moon, the rest of the Dragon Team suspect that Gokū is the monster that killed his grandfather, and they cringe in fear at the prospect of Gokū becoming that monster. Oolong suggests that Gokū should look at the moon to see if he is the monster, but Bulma claims that is a bad idea and instructs Gokū to desist from looking at the moon. However, Gokū looks at the moon anyway, injecting fear into the rest of the Dragon Team, but nothing happens. Soon after, Gokū then undergoes the transformation into a giant monkey, waking up Pilaf and his subordinates by breaking through the steel-walled, glass-ceiling prison.
