L'Eau sacrée

Goku attempts to snatch the sacred water from Korin with his "After Image" technique which is no surprise to Korin. The next day Korin gives Goku a Sensu Bean to last Goku's appetite and energy for 10 days. Korin throws Goku's dragon ball out of the tower forcing Goku to run down and up the tower again. Goku attempts to take the sacred water while Korin sleeps, but thinks better of it. Goku tries long and hard for the next two days to get the sacred water. Mercenary Tao realises how he wasn't able to kill Goku. Goku attempts to read Korin by mimicking his every move. The very next day, Goku finally manages to get the sacred water. To his disappointment it doesn't strengthen him, but all that exercise did him good. Tao kills the tailor who made his outfit before leaving.  (Source: Wikipedia)
