Ratchet And Clank
Wait until the credits end when you complete the game to view a commercial featuring Captain Qwark.
After receiving the metal detector, go back to previous planets and search for hidden Bolts. Not only does the metal detector help you find more, but the planets' items also respawn after you leave it.
Note: This also works with the Vacuum Gun. Perform a Comet Strike at far away Bolts. If the wrench passes near them, it will attract the Bolts to you. This is especially useful around water or Bolts that are across chasms.
