Ratchet & Clank Cheats

Suck Cannon
Use the Suck Cannon while on the planet Pokitaru. On that planet, the path to get the Oxygen Mask, is treacherous.
The best weapon to use is the Suck Cannon. Stand at the bottommost part of the Resort Owner's raft and hold down [circle] to activate the Cannon while pointing it at the Resort Owner. The Puffer fish will almost leap into your Cannon, making the path a breeze, to contiune on.
