Kaettekita Dr. Slump: Arale-chan Special

Years after the familiar chaos of Penguin Village, old friends gather again as life reaches a new milestone: Tsukutsun and Akane are preparing to marry, and even Turbo has grown older. Their reunion quickly becomes a reminder that ordinary celebrations rarely stay ordinary when Arale, Senbei, and the rest of the village are involved.

Amid the new festivities, a wild adventure centered on the treasure of Nanaba Castle brings back the absurd inventions, impossible accidents, and cheerful mayhem that have always followed Arale wherever she goes.
