* EarWorm: The main theme. ''Doo doo doooo...''
* CompressedAdaptation[=/=]PolishedPort: The Flash version of ''World 3'', though it does not have a good portion of the consoles' content, is a very respectable and full game in its own right.
* GoddamnedBats: The ninjas in ''World 3''. They're small, they can't be stunned, and they tend to appear in large groups.
* ShoutOut: The fighting controls for the pencil in ''World 3'' reflect those of Fancy Pants Man's combos in ''NewgroundsRumble'', since Borne designed every aspect of FPM's inclusion in that game.
