Due to a conspiracy, Goku and his friends are turned small.
In order to fix things, they'll head off to a new world!
It's a grand adventure with intense action in an unknown and mysterious world.
Since Goku has to make up for his petite size, he uses his Nyoibo (Power Pole) to right, something not seen in a long time.
