text: The Plumber The Plumber (voiced by Neil Flynn in the first three games, Jess Harnell in later appearances) is a staple of the Ratchet & Clank series. He almost always appears with his rear end sticking out of whatever he is working on, and can be surprisingly helpful when he appears. In Ratchet & Clank and Going Commando, the Plumber is an NPC that appears on separate occasions.  Once later in Going Commando, he sells Ratchet an item to exchange for another. In Up Your Arsenal, he returns to ask Ratchet to search for Sewer Crystals, which he will trade bolts for.
  The Plumber does not appear in Ratchet: Deadlocked; although the credits state that he had been called away to deal with a "sump pump emergency in the Rygylian Nebula". He appears with a non-speaking role as a memory in part of a dream-state world level in Ratchet & Clank: Size Matters, and also appears in Secret Agent Clank to fix the showers at the prison in which Ratchet is incarcerated, returning them to their typical freezing cold temperature.
  The Plumber returns in Ratchet & Clank Future: Tools of Destruction, with a new updated design, wearing glasses and having a more detailed outfit. He provides Ratchet with a spare part for the Dimensionator that proves valuable in the game's climax. He then appears once again in Ratchet & Clank Future: A Crack in Time in Clank's memory banks. When Clank shows up, The Plumber states that he "must've taken a wrong turn somewhere" and mistook it for Qwark's mind because of the "emptiness". He then tells Clank "I wouldn't risk any more than six minutes", a piece of advice that ultimately allows Clank to save Ratchet from death by reversing time.
