It's time for another lighthearted adventure in Ooo, you know, with death, the underworld, and heavy metal (ROCK ON!!!) Finn and Jake go on a mission to retrieve a soul from the land of the dead. Mahadopus shares the secrets of what happens in the Muslim-hereafter, while Rosecat draws on Death imagery from all over the world. Most importantly, her royalness Empress Velvet, light of all that she surveys and protector of the fleece sleep sack, makes demands for sustenance; ten cases of crisy lettuce. Or else, she shall rain doom down from the heavens. The humans have a limited time window to comply.
