I was hoping to take this home as a souvenir, but I guess I have to use it:
So you are reading the sign and learning about how the mind is truly the center of your life - processing and interpreting every moment of your experience. You start playing with the plastic brain mold when you notice something shiny underneath the kiosk.
You reach down, pick it up, and realize it is the IDOL OF THE BRAIN
This is the 2nd most powerful Idol. If the most powerful idol is played at the same time, it will negate this idols powers.
