Ep. 51: Liu Xing Long! Find The Big Tornado Attack's Weak Point

Goku, Pan, and Giru find the six-star dragon, Oceanus Shenron, in a fishing village. She reveals that she was created by the very first wish that Goku and company ever made (Oolong wishing for a pair of underwear in order to thwart Emperor Pilaf); while both she and Pan are disgusted and embarrassed by this, Goku looks back on it with humor, much to the dragon's anger. This dragon can put up energy shields, so Goku can't hit her. He tries to use a Kamehameha wave, but the dragon deflects it. The dragon then creates an extremely powerful vortex, smashing Goku through a cliff. Pan creates her first Kamehameha wave and blasts it at the dragon, which gives Goku the chance to deal the finishing blow. They collect the six-star ball and continue their journey. (Source: Wikipedia)
