Wokay, so King Kai decides to give Arale a big job
She is tasked to replace Bills' brains with a pile of poop, to complete her mission the God of Destruction is detained in an indestructible* harness that keeps his head exposed (think of it as a pillory). This harness negates/rebounds back all of his 'offensive/non-defensive' powers, and since Bills is strong Arale will keep punching his skull until it breaks (give her a good 100 years) so that she can replace his brain with poo.
Will she clear this challenge with these requirements?
*as in cannot be destroyed in any way or form
