Gandalf returns to the Shire for Bilbo's "eleventy-first" (111th) birthday party, bringing many fireworks for the occasion. After Bilbo, as a prank on his guests, puts on the Ring and disappears, Gandalf strongly encourages his old friend to leave the ring to Frodo, as they had planned. Bilbo becomes hostile and accuses Gandalf of trying to steal the ring. Alarmed, Gandalf impresses on Bilbo the foolishness of this accusation. Coming to his senses, Bilbo admits that the ring has been troubling him, and leaves it behind for Frodo as he departs for Rivendell.
