The unicorn known as Gravi has skills in tactic military measures in which those of neither brawn of brains can outwit him.

But it’s not so easy, especially when the opponent can quickly regenerate & is at a feat to being invincible, the gang must find the ‘core’ to the solution. Can it be done at all…?
