Geppetto's Boat is the vessel Geppetto uses when he goes to sea and searches for Pinocchio. It is unknown how Geppetto obtained the ship, but it presumably happened after Pinocchio was bought by Stromboli. The ship is shown to have several rooms, including a bedroom. Also attached is a small raft.
At some point, Geppetto's ship was swallowed whole by Monstro. Geppetto attempted escape at several points, but each attempt failed as Monstro only opened his mouth while eating. After Pinocchio arrives, the puppet uses scrap wood from the ship 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 ship remains in Monstro's stomach.
The boat was located inside the belly of Monstro in a place where Geppetto, Figaro and Cleo were stranded with nothing to eat. Eventually, Pinocchio found himself on Geppetto's boat, and the woodcarver was relieved to see his son again but still unable to get out of the whale. However, Pinocchio gathered some wood and started a fire, which caused Monstro to sneeze the boat out. Furious, Monstro chased the boat, which was smashed to pieces with his tail.
