Trivia

 * The funny exchange between the lot as the Powerpuff Girls save the blimp ("Look! Down in the sky! Is it a bird"? "Maybe a plane?" "No, it's the Powerpuff!") riffs on a cliché line from Superman, as does the John Williams-esque music that plays immediately afterwards.
 * When Buttercup beats her chest and does a roar, she's parodising Kong when he;s beaten robotic theropods on the 2005 version of King Kong.
 * Velma ponders 'To be or not to be... that is the question'.... a well-known quote from William Shakespeare's Hamlet.


 * When the lot first encounter Mojo Jojo, he runs off in traditional Road Runner fashion, accompanied a slide whistle sound cue.

Shortly afterwards, the lot fall into Mojo's lair- in classic cartoon fashion, they briefly hang in the air for a few seconds before falling; their weapons stay suspended for even longer.
 * The scene when HIM took snake-form when about to trick Velma is a nod to the Serpent who tricked Adam and Eve to eat the Forbidden Fruit on the Bible.
 * Buttercup's annoyed complaint 'Another mess you got us into, eh ' is based on a well-known quote from Lauren and Hardy.


 * Buttercup says 'It's clobberign time'.... the Thing's catchphrase from The Fantastic Four.
