Geppetto's Boat is the vessel that Geppetto uses when he goes to sea to search for Pinocchio. It is unknown how he obtained it, but it presumably happened after Pinocchio was bought by Stromboli. It is shown to have several rooms, including a bedroom. It also has a small raft attached to it.
At some point, the boat was swallowed whole by Monstro. Geppetto attempted to escape at several points, but each failed as Monstro only opened his mouth while eating. After Pinocchio arrives, he uses scrap wood from the boat to create a large fire that makes Monstro sneeze. Geppetto and Pinocchio are then able to escape on the small raft. Presumably, the rest of the boat remains in Monstro's stomach.
