Lake Knights

The Lake Knights make their appearance in My Two Favorite People. When Jake tried to spend more time with both Finn and Lady Rainicorn at the same time, he realizes this can only be done if he fetches the universal translater that he threw into the lake. The Lake Knights guard the lake, translator, and a massive pile of doubloons and treasure (which remain untouched by Finn, Jake, and Lady Rainicorn). After fighting off a horde of the Lake Knights, the three get the translator and leave undamaged.
