Poketto monsutâ - Season 17 Episode 10

As long as our heroes are in Miare City, Serena suggests they visit Dr. Platane before they continue their journey–and she's made a batch of delicious macarons for the occasion. At the doctor's lab, they settle in with a nice cup of tea, only to discover the macarons are missing. They find the basket of treats in a corner, guarded by a very hungry Harimaron who isn't interested in sharing. Meanwhile, the Rocket-Dan has been researching Dr. Platane's studies on Mega Evolution, and the villains decide stealing his data would be a big boost to their schemes. They break into the lab grounds, grab the professor, and throw him in the back of their truck, but Eureka and Serena manage to sneak aboard before they drive away. The girls get locked inside by accident, but Serena manages to leave a trail of broken macarons–which Harimaron quickly sniffs out, leading Citron and Satoshi to the villains' hideout. In the meantime, Kojiro has plugged Dr Platane's data into a mechanical Mega-Mega Nyarth, which attacks our heroes. Harimaron lets Citron know it wants to battle, but neither Harimaron nor Pikachu can make a dent in the mighty machine. But then, the Mega Bursyamo that rescued Satoshi when he fell from Prism Tower reappears, along with its Trainer, a mysterious man in a Bursyamo mask. Mega Bursyamo's incredibly powerful Flamethrower leaves Mega-Mega Nyarth charbroiled, along with the actual Nyarth who's been controlling it, and the Rocket-Dan is sent blasting off again. As our heroes head back to the lab with the doctor, Mega Bursyamo's Trainer is watching over them–now without his mask. It's Limone, Citron and Eureka's dad. At the lab, Satoshi, Serena, Citron, and Eureka are saying their farewells. Citron thanks Harimaron for its help against the Rocket-Dan and says they'll meet again soon, but it seems clear that Harimaron wants to come along. And so, with Citron's friend Harimaron now part of the group, the journey to Shoyo City continues.
