Glad to see this is still popular. The most memorable part was the ending. It's mostly because of how weird it is. It's weird even by the standards of this series. It features Salad Fingers getting his head eaten by a clone. Or was that the clone?
It makes as much sense as anything else. I notice that this is the first time he talked in a different voice when speaking through his puppets. That's a sign of insanity. I like that horse. I'm a brony, BTW.
