Densetsu no Starfy 4

He may be the prince of a kingdom in the clouds, but Starfy's not afraid to get his pointy hands dirty pummeling bad guys. Watch out, villains - Starfy and his gruff-talking sidekick clam, Moe, are setting out on another astonishing adventure: to help a mysterious, bunny-eared visitor find his lost…

A short time after Densetsu no Starfy 2, everything was calm and everyone including Stafy was happy again, until another severe thunderstorm came and shook Pufftop Palace. This time, it is more severe than the ones in the past. A lightning struikes the Magic Jar, destroys it and Ogura is free again.

Stafy is now back at Pufftop Palace, playing with his friend Moe. Ogura, imprisoned inside the Magic Jar, unleashes his children into the sky. Ogura's children cause a series of thunderstorms and earthquakes that shake Pufftop Palace, causing the Magic Jar to shatter and release Ogura.

In the beginning, Starfy was moving things around Pufftop Palace, until he tripped and dropped some things he was moving. One of them fell into the ocean, which was the Magic Jar, an object that seals the evil being known as Ogura.
