thanks! you can hear a lot of it on this recent (candid!) interview i did

Ricks join in the Halloween party, everyone have fun. But suddenly some magic power transform them became the character that they dressed for, but 399 seemed to have no breath.

Aurick, who dressed himself as an ordinary Rick but really lost his magic power, tried to create a device to bring his friend back...

Unfortunately, no one knew or could see that 399 had actually become a ghost, he just wandering around Aurick until the crowd leaved.
