Two weeks later, Ratchet headed to planet Aranos to infiltrate a Flying Lab, and then attempted to retrieve a stolen Protopet experiment of Megacorp's, from an unknown thief.

The thief evaded Ratchet persistently, capturing Clank from his apartment and holding him hostage. The two reunited when Clank freed Ratchet from a locked room and eventually retrieved the experiment on planet Siberius. After meeting with Fizzwidget, and "accidentally" being ejected from the ship on planet Tabora, Ratchet and Clank met with the Thief to learn about the true means of the experiment. The two investigated the Testing Facility on planet Dobbo, and found more and more information, culminating into the true means on planet Todano, which the duo attempted to put a stop to in Silver City by talking with Fizzwidget. Ratchet then made the mistake of threatening a robotic copy of Fizzwidget with the Thugs-4-Less leader watching, who arrested them. After they broke out of jail and freed Angela on planet Snivelak at the Thug Headquarters, Ratchet and Clank then investigated a Distribution Center and found out that Allgon City was undergoing a disaster, and may had lived up to its name at the hands of rampaging Protopets. As well as that, they headed to planet Grelbin to find Angela, who gave them the key to get into a Protopet Factory, in the heart of the Megacorp Headquarters on planet Yeedil. Once there, they soon found out that the Fizzwidget they knew, was really Captain Qwark. He accidentally mutated the real Protopet into a giant monster that ate him. Ratchet defeated the Mutant Protopet, at which point it coughed up Qwark and Angela's Helix-o-Morph. She used it to cure the Protopet of the Monsterpropanase in its system, later using it to cure all the Protopets in the galaxy. Ratchet's main optional easy-to-get-to weapon is his OmniWrench 8000 v3. Ratchet's vehicle (Star Explorer), was a MegaCorp vehicle that Ratchet seemed to fulfill his commando missions from Abercrombie Fizzwidget. The Star Explorer was fittet with duel standard fusion laser cannons, auto-lock misill chargers, standard shielding, and upgradable-degradable booster engines. You can purchase upgradable "stuff" with raritanium.
