The Collective is hungry to collect more spirits and bodies to absorb, making it an even scarier and more powerful being, but it is not enough...so it begins to chase after the most delicious of memories. Bowen and Po Po get taken by the Collective, and it's up to Xanthe and BatgirI to pull them out of its conjoined body parts before they get melded on as well--permanently!

As Po Po fights to hold on to her memories as much as possible, we discover her secret origin and why she has such a soft spot for orphans...
