Sir Grapevine is Princess Luna's slow-witted assistant when it comes to business with the Steed Knights.
Despite being honest, loyal, and well organized; there is virtually nothing that Grapevine actually understands. He is so good-natured that his inability to discern sarcasm will always be forgiven. He seem to annoy the princess every now and again.
"The less he knows, the better."
Sir Grapevine was modeled after Agent Larabee from Get Smart.
Sir Grapevine is one of the Steed Knights in the long line of Sir Sheath's predecessors.
