when you go beyond the grotto

Haha

Given that all episodes are paired together and share a common theme with each other, I'm excited to see what common theme the creators choose for Beyond the Grotto and LR and the Crystal Dimension

It's about the water nymphs

Beyond the Grotto features Finn and Jake finding a sea-lard in the ocean and following it to a mysterious place. It comes out on the 9/4/16
