Pokemon the Series Season 19 Episode 31 A Gaggle of Gadget Greatness!

Ash and his friends are on a journey through the Kalos region, and their latest stop is Lumiose City, where they come across a technology expo. The group is excited to see all of the gadgets and machines on display, but things take a turn when Clemont's younger sister, Bonnie, wanders off and gets lost in the crowded event.

As they search for Bonnie, Ash and his friends stumble upon a stand run by a young inventor named Chespin. Chespin has created a device that can detect Pokémon nearby and he's offering it for sale. Ash and his friends are interested in the gadget and they ask Chespin to let them test it out.

The group eventually finds Bonnie, who is in the middle of a Pokémon battle with Chespin's rival, an inventor named Belmondo. They watch as Belmondo uses his state-of-the-art gadgets to control his Pokémon in battle, but eventually Chespin jumps in and helps Bonnie win the battle using his own gadget.

Impressed by Chespin's invention, Ash and his friends agree to help Chespin compete in a gadget contest being held at the expo. The contest challenges inventors to create the most innovative and useful gadgets, and the winner will receive a prize of 10,000 Pokédollars.

Chespin and Ash's team work together to come up with a unique invention that will catch the judges' attention. Meanwhile, they have to fend off Belmondo, who will stop at nothing to win the contest and prove that his gadgets are superior to Chespin's.

The competition heats up as the teams pitch their inventions and show off their gadgets. While Chespin's invention is unconventional and less flashy than Belmondo's, it proves to be incredibly useful and the judges award Chespin the grand prize.

As the episode ends, Ash and his friends continue on their journey through the Kalos region, eager to see what other adventures and challenges await them.
