Poketto monsutâ - Season 17 Episode 17

During our heroes' journey to Shoyo City, Satoshi and Keromatsu meet a young ninja named Sanpei and his Gekogashira. Satoshi challenges them to a battle, and Gekogashira defeats Keromatsu with an impressive Quick Attack. Sanpei is about to take his leave when Satoshi asks him for some special training–he's never seen anything like Gekogashira's Quick Attack, and wants Sanpei to teach Keromatsu how it's done. Sanpei agrees, and Keromatsu enters ninja training–and thanks to Serena's costume skills, Eureka, Dedenne, and Pikachu get to play ninja too. After Sanpei takes Keromatsu through a series of exercises designed to increase its speed–chasing Gekogashira as it jumps swiftly from rock to rock, leaping through the trees at an incredible pace, even moving its feet fast enough to run on water–Keromatsu is finally ready to try its own Quick Attack. Just then, their training is interrupted by Musashi, Kojiro, and Nyarth, who have grand plans to nab Keromatsu and Gekogashira and form their own ninja Pokémon squad for the Rocket-Dan. They manage to net Gekogashira and Pikachu, but Keromatsu is just too quick for them–so quick, in fact, that it starts to create an illusion of being in many places at once. This unexpected Double Team attack overwhelms the villains and sends them blasting off again. With all the Pokémon safely returned, Sanpei thanks our heroes for saving Gekogashira, and Satoshi reminds him that without his generous training regimen, Keromatsu wouldn't have acquired the skills that allowed it to rescue Gekogashira. And so, saying their goodbyes, our heroes once again hit the road for Shoyo City, site of Satoshi's next Gym battle.
