Fionna and Cake – with the help of the former Ice King, Simon Petrikov - embark on a multiverse-hopping adventure and journey of self-discovery. All the while a powerful new antagonist determined to track them down and erase them from existence, lurks in the shadows.

Bee is a young lady trying to make her way in the world. She often acts before thinking, which can lead her into trouble (and adventure!). She also has a strong, nurturing personality, and doesn’t think twice about taking in Puppycat when he needs help. Although her laid-back-space-casey attitude and lack of skills tend to keep her from maintaining a job for long in the human world, she isn’t someone who easily gives up, and with the experiences she gains at the magical temp agency she stumbles on, she’ll finally have the chance to find out what she’s meant to do with her life.

Kent is turning 50. He's not thrilled about it. His plans for a fun weekend with Sarah are upended when his friend Kev unexpectedly arrives to build him a wall.

On a charming magical island, the impulsive Bee and her furry pal get up to all sorts of adventures while working for an intergalactic temp agency.
