To Master the Onixpected
The episode starts with Brock and Ash watching a TV show with all of the trainers of the pokemon league in it. Bruno, Agatha, Lance, and Lorelie are all in it(it's a show of them all fighting, like the one ash is watching in the first episode).
Bruno appears to be fighting really hard, but Ash has to continue his training for the pokemon league.
They decide to go visit Bruno, the rock and fighting type trainer for tips on how to train his pokemon.It is rumored that Bruno lives in the mountains where large Onix's roam around. The gang head for the mountain but are confused when they reach the side of the mountain. A large track was made in the rock, as if someone dragged something heavy on it. It lead a path to the top of the mountain.
Then, a large Onix comes charging at them angrily. The large onix is much larger and heavier than most onix. Bruno pulls them of the track behind a large boulder to save them. Bruno brings them to his home, a cave at the top of the mountain.
Ash and co. thank Bruno for saving them from the onix. Bruno explains that the onix grew so big because of the fertile soil and rock on the mountain. Ash asks Bruno for his wise advise, but bruno refuses to tell him. Bruno then suddenly turns into a lazy slob. He stops caring about his guests. Then the large onix attacks them again. Onix still rages after several attemps of overpowering it by Misty, Ash and brock but Bruno sooths the large Onix. He reaches inside one of the crevices of Onix and takes out a Sandslash. Apparently the Onix normally was a calm creature but lately had a pain on him. Again, Ash is sidetracked from his training for the pokemon league as they return home.
