Fiona and Cake are under new management during the February 18th episode, Bad Little Boy!
According to leaked plot details, the princesses are completely sick of the Ice King's insane Fiona and Cake fanfiction, so Marceline swings by the Ice Kingdom to show him how it's done.
Based on the duet below, she is way better at it. No offense Ice King.
Neil Patrick Harris will also be reprising his role as Prince Gumball for the episode. Does this mean Marceline is writing a LOVE TRIANGLE?
