This episode is amazing, nearly made me cry. It was very very close between this and The Dark Cloud, but this one feels bigger. It gives an originally 1 dimensional villain more development, making him feel way more sympathetic than before, and also recontectualizes a lot of stuff from past episodes, such as Finn being afraid of water. This episode is the peak of Adventure Time's story arcs, the Islands arc in general is peak adventure time, the entire top 5 for this season is filled with them. Oh yeah, also this episode is gorgeous, Islands in general had fantastic backgrounds and this episode in particular is a marvel to look at.
