Trying to overcome negative thinking and fixed mindsets, Yet and the Band of Believers set out to stop the evil Not twins in Negatropolis from taking over the world.  Can and Will Not rule Negatropolis and have their eyes on the prize of Positivity City in order to create a world where everyone can’t and won’t change.  It’s up to Yet to show the citizens of all the cities that having a positive growth mindset is the best way to learn and think.
