Pokemon the Series Season 15 Episode 48 Meloetta and the Undersea Temple!

Ash, Iris, and Cilan continue their journey through the Unova region and arrive at an island where a festival called the Meloetta Festival is held every year. Upon arrival, they meet an elderly man named Ridley who tells them about an ancient Undersea Temple that is said to have a mystical power that can bring peace to the world.

The group is intrigued by this and decides to investigate the temple. As they make their way there, they encounter a mysterious Pokemon called Meloetta who seems to be drawn to the temple. Meloetta is a musical Pokemon that can change between two forms, Aria Forme and Pirouette Forme, depending on the type of music it hears.

When they arrive at the temple, they find that it is guarded by a group of Pokemon called the Guardians of the Temple. The Guardians tell them that no one is allowed to enter the temple without the permission of Meloetta, who is the only one who can calm their protective instincts.

Ash and his friends set out to find Meloetta and bring it back to the temple. Along the way, they meet a group of researchers who are studying Meloetta's ability to change forms. The researchers explain that Meloetta's power comes from a special melody that can only be played on a special instrument called the Reveal Glass.

As they search for Meloetta, they encounter a group of villains called Team Rocket who are also after Meloetta. Team Rocket plans to use Meloetta's power to take over the world. Ash and his friends team up with the researchers to stop Team Rocket and protect Meloetta.

Finally, they find Meloetta and bring it back to the temple. Meloetta begins playing the special melody on the Reveal Glass, which calms the Guardians and allows them to enter the temple. Inside, they find an ancient artifact that holds the power to bring peace to the world.

As they leave the island, Ash and his friends feel a sense of accomplishment and wonder what other adventures await them on their journey through the Unova region.
