Mild violence: (This is the second in the series) After defeating the last game's villain and saving the galaxy, Ratchet and Clank became famous, and in turn, have had lots of down time. That is, until a person named Abercrombie Fizzwidget, the owner and CEO of Megacorp, calls them up and asks them to retrieve a stolen project of his, dubbed, "Protopets." When they finally track down these Protopets, they find that the Protopets are extremely vicious and can multiply at an alarming rate—and they've started to attack everyone who's bought them. Now to destroy them...

The story itself is full of silly, slapstick, sarcastic, and clever humor, with many lines like, "Ask yourself—are you man enough? Hero enough? Insane enough to step in the ring with two of the fiercest warriors in the galaxy? If you answered yes...you're a big fat liar!" There are also more of these promos that advertise Megacorp's Protopets, and involve the narrator talking about how adorable the Protopets are, while it shows the exact opposite on screen. So in other words, it is sarcastic and a bit over-the-top, but pretty harmless, cartoony, and all done in a fun, light tone.

The violence is very fantastical, with mass explosions, crashes, constant fire from the enemy, utter mayhem and frantic chaos. And although you will fight a variety of wild creatures, the majority of your enemy consists of several different types of robots. Ratchet will be fighting them with a couple of dozen (fully upgradeable) weapons. The majority of these weapons have exaggerated and ridiculous fire-power, like a lava gun, a gun that shoots saw blades, a rocket launcher, and even a gun that turns enemies into sheep. Ratchet can also attack enemies with his wrench. When Ratchet disposes of an enemy, it will explode into a cloud of bolts (currency), metal (if it's a robot), colorful firework-like particle effects, and/or puffs of smoke. Beyond this, the overall tone of violence is mild, the cutscenes' action is comparable to Looney Toon's over-the-top antics, and the actual gameplay is no worse (in fact, maybe more mild) than the sometimes chaotic and moderately violent cartoons kids watch today.

Mild language: (The ESRB didn't mention this in their rating, although it's mild) Near the end, one of the main characters says, "Alright, just what the **** is going on!?" But the entire word is bleeped out; there's no way to tell what she said.
