Navigate the sewers and Bring raritanium to inventor are missions in Ratchet & Clank. Ratchet and Clank found a teleport in Jowai Resort, inviting them to explore the "scenic" sewers. At the end of the sewers, completing the "Navigate the sewers" mission, he ran into the Inventor, who was looking for Raritanium. He tried to mind control them with the Persuader, but failed and offered to trade it for Raritanium instead. Later on, after acquiring Raritanium (in the mission "Explore the Icy Wastes"), he traded it for the Persuader, despite the Inventor trying again to "persuade" Ratchet to collect more of it for him.

Completion of the latter mission in the PlayStation 3 and PlayStation Vita versions of Ratchet & Clank will unlock the bronze trophy These are not the droids you're looking for....

Walkthrough[]

Upon entry of the sewers, jump into the water and dive through the underwater doorway on the right, entering a room with a lone amoeboid and Insta-Faucet. Use the Hydrodisplacer to drain the water, and then return to the first room and use the Trespasser and a now accessible Invinco-Lock. Return the water using the Insta-Drain and then swim to the new room, where a group of five large amoeboids roam around. Dispatch them and then climb up the platforms placed intermittently in a staircase pattern on the walls. The red-colored blocks are stable, though the yellow will swing akin to a seesaw.

At the top you must pass another Trespasser puzzle, after which you are to swim through a long underwater tunnel, finally emerging into another room inhabited by amoeboids. Defeat these five, perhaps using a nearby platform as a safe vantage point, and clear the final Invinco-Lock to enter the last room. Talk to the Inventor, and upon acquiring Raritanium elsewhere, return here to trade it with him.
