I SERIOUSLY THOUGHT THAT COOKIE WAS WORKING FOR THE LICH.

That cookie wanted PB's crown. In Mortal Folly, PB rubbed her crown jewel and protected herself from the Lich's mind control OF DOOOOOOOOOOOOOOOOOOOOOM! If that cookie really DID work for the Lich, he would've smashed the crown, so the next time the Snail (possesed by the Lich, btw) comes near PB, she will get mind-controlled and resurrect the Lich, and then OOO WILL BE DOOOOOOOOOOOOOOOOOMED!

WHOAHAHAHAHAAAAAA!
