* FreezeFrameBonus: ''Scribblenauts'' was developed by 5th Cell. Go look at their logo. Now go look at the cover of the notepad Maxwell holds on the cover of the first game.
* HeyItsThatVoice: JenniferHale voices Lily, who narrates ''Unlimited'''s opening and ending cutscenes.
** ''Unlimited'''s cutscenes are animated by Paul Robertson, of ''WebAnimation/KingsOfPowerFourBillionPercent'' / ''VideoGame/ScottPilgrim'' / ''[[Recap/GravityFallsS1E10FightFighters Fight Fighters]]'' fame.
** In the Mexican Spanish version, Lily is [[Manga/{{Naruto}} Naruto Uzumaki]] and [[Manga/CardcaptorSakura Chiharu Mihara]].
* KillerApp: Even before its release, millions of DS units were sold just for the game.
* RecursiveAdaptation: ''Unmasked'' contained a tie-in comic as a pre-order bonus.
* ThrowItIn: When someone actually succeeded at "Stump The Dictionary" at E3 (like with "plumbob"), the devs made a note to add the word before release. They also threw in the references to Feep's famous post.
