Dr. Slump N-cha! Arale no Oshioki! Idea Dorobou wo Yattsukechae

Penguin Village is shaken by a very particular kind of trouble: an idea thief. With inventions and creative work at the center of the commotion, Arale charges into the problem in her usual unstoppable fashion while Senbei and the others confront what happens when someone treats another person's ideas as their own.

Behind the chaos lies a practical question: how can an inventor protect something they created? As the chase unfolds, patents and the steps used to protect inventions become part of the solution, giving Arale one more reason to make sure the idea thief does not get away with stealing someone else's hard work.
