Finn's right arm has been a subtle highlight of Season 5.
*Finn's future self in both Puhoy & Dungeon train have a whip or pillow arm.
*Finn's past life Shoko received a cybernetic right arm shortly before dying.
*Ice Prince Finn/Farmworld Finn from an alternate universe has a cybernetic arm.
*The Grass Blade is cursed to permanently stay on Finn's right arm. Loosing his arm would either lift the curse or the blade would create a grass arm.
