The 5th game in the ''Franchise/RatchetAndClank'' series and first on the [[UsefulNotes/PlayStationPortable PSP]], later ported to the UsefulNotes/PlayStation2. It is the first of the two spin-off games in the series, released by High Impact Games, and is infamous for it's call-backs to the original trilogy.

It revolves around a [[IncredibleShrinkingMan shrinking device]], a kidnapped child, as well as Captain Qwark trying to find his lost parents.

!!This game contains examples of:
* AcidTripDimension: Dreamtime. Let's see, you have Flying Needles and Captain Qwark masked as doctor and throwing'' chainsaws'' at you as enemies, location combines Pokitaru, Veldin, Endako, precisely Megapolis, and some other locations, there are bolt crates that have fourth of their usual size, mirrors from which enemies fly (and if you shatter it, [[NiceJobBreakingItHero instead of one enemy flying from entire mirror there will be enemy flying from each shard]]), eyeballs with literal red glare that will [[OneHitKO kill you]] if you're spot, Sprout-O-Matic plants having head of Qwark that transforms into swingshot target once swung off, and finally [[spoiler: The boss fight against Giant Clank whose attacks generate waves of butterflies (that still damage you)]]. And background isn't less trippy either, with green void full of floating 2D sprites of previous [[BigBad Big Bads]] and some other characters.
* AfraidOfNeedles: Flying Needles serve as enemies in Dreamtime.
* BarefootCartoonAnimal: Ratchet, as he wears his outfit from the first game. He can use shoes later in the game.
* BattleInTheCenterOfTheMind: Well, not really a battle, but near the end of Dreamtime, Ratchet is put into a boss battle against [[spoiler: a dream version of Giant Clank]].
%%* BigBadDuumvirate: Otto Destruct and [[spoiler:Luna]].
* CallBack: Otto's monologue before the final boss fight is very similar to Drek's monologue at the end of the first Ratchet and Clank.
* CanonDiscontinuity: [[http://www.insomniacgames.com/community/showthread.php?56339-Did-Insomniac-Ever-Outright-Confirm-SM-and-SAC-Were-Non-Canon&p=1421220&viewfull=1#post1421220 Insomniac Games confirmed]] that this game and ''Secret Agent Clank'' are non-canon to the main games. ''[[VideoGame/RatchetAndClankIntoTheNexus Into the Nexus]]'' likewise ignores mentioning both games in the Insomniac Museum.
-->"We have always treated them as non-canon while making our games. However, he have done joke nods to them."
** The game is canon in the Japanese version, however.
* ContinuityNod: Several in Ratchet's dreamscape, like Clank's apartment in Bogon and larger form. Then there's this exchange, which mirrors a conversation from the original game.
--> '''Ratchet:''' There she is! Let's get her!
--> '''Clank:''' Ratchet, do you notice anything... unusual about [[spoiler: Luna]]?
--> '''Ratchet:''' Well, she ''does'' seem to have an unusually large door coming out of the back of her head.
--> '''Clank:''' And why do you think that is?
--> '''Ratchet:''' She's... uh... a robot?
* ConverseWithTheUnconscious: Clank does this to a comatose Ratchet midway through the game. [[spoiler:Ratchet was able to hear him, which allowed him to wake up]].
* CuteIsEvil: [[spoiler:Luna]].
* DaddysLittleVillain: [[spoiler:Luna may count as being Otto's "child". After all, he '''created''' it for his evil intentions.]]
* DeadlyDoctor: Ratchet dreams of Qwark clones as chain sword throwing doctors while in Dreamtime.
* DeepSleep: [[spoiler:Luna's mooks force Ratchet into a coma after they capture him. It's at this point where he "visits" Dreamtime]].
* DeliberatelyDistressedDamsel: Luna spends the first 1/3 of the game imprisoned in Kalidon, guarded by Mungo. The heroes defeat the monster, but find out that [[spoiler: "she" [[{{FakedKidnapping}} faked her own kidnapping]] just so it and it's "friends" can kidnap '''them'''!]]
%%* DisneyAcidSequence: Dreamtime.
* DisneyVillainDeath: [[spoiler:Luna, following its defeat. Unlike most examples, we see it hit the ground, '''HARD'''.]]
* DreamLand: Ratchet ends up in a nightmarish version following [[spoiler: his capture by Luna]].
* EnfantTerrible: It's not everyday that you get to fight [[spoiler: an evil robot built to resemble an innocent young girl...]].
%%* EvilAllAlong: [[spoiler:Luna.]]
* EvilGenius: Otto Destruct. [[spoiler:His goal is to become the most intelligent being in the galaxy by extracting intelligence from others.]]
* {{Expy}}: Otto and [[spoiler:Luna]] can be viewed as evil counterparts of [[Literature/{{Pinocchio}} Geppetto and Pinocchio]]. Both Otto and Geppetto are inventors, while [[spoiler:Luna]] and Pinocchio are puppets very valued by their creators and even strongly loyal to them.
* TheFakeCutie: [[spoiler:Luna. It was built to resemble a little girl to lure Ratchet into a trap.]]
* FakedKidnapping: Luna during the first third of the game.
* FantasticVoyagePlot: [[spoiler:Ratchet goes inside Clank to reboot him after he is attacked by Technomites.]]
* FlatEarthAtheist: Ratchet's skepticism of the existence of Technomites, dismissing them as just an old fairy tale. [[spoiler: Naturally, he gets proven wrong.]]
* GameBreakingBug: On your second or third playthrough (PSP version), the Omniwrench all of a sudden stops damaging 90% of your enemies. This will never go away, on every subsequent playthrough. The [=PS2=] version is not affected.
%%* IncredibleShrinkingMan
* MakeMyMonsterGrow: [[{{TheMovie}} The Game]]
%%* ManipulativeBastard:
%%** [[spoiler:Luna.]]
%%** [[spoiler:Otto.]]
* NewGamePlus: Of course. But to get everything, you have to go through the game ''three times''.
* PermanentlyMissableContent: The "Friends Don't Hurt Friends" skill point is lost until a NewGamePlus if you took damage during the Giant Clank "fight" and beat the "battle", as it doesn't reappear after you win.
* SpaceBattle: Clank goes through two of these throughout the game.
* TookALevelInJerkass: Ratchet. His personality in this game is similar to the one in the [[VideoGame/RatchetAndClank first game]], especially during the first 1/3 of the game.
* WalkingShirtlessScene: Ratchet, as he wears his outfit from the first game. He can use a shirt later in the game.
* WouldHurtAChild: [[SubvertedTrope Subverted]], as [[spoiler:the child in question turns out to be fake]].
