* The scene where King Goobot's army abducts all of the adults of Retroville, accompanied by eerie music.
** The manic look in Goobot's eyes when he first sees Jimmy's parents.
-->They look... ''delicious''.
** Special mention that we hear Hugh and Judy's terrified screams as they're individually kidnapped by the aliens via being sucked up by shafts of light from the spacecrafts.
*** However, Judy's scream suddenly becomes {{Narm}} when you realise it's a StockSoundEffect.
* Poultra and her appearance can make people afraid of chickens.
* The apple worm from Ms. Fowl's point of view after being shrunk down to the size of an ant by Jimmy's Shrink Ray. Especially its ''[[MoreTeethThanTheOsmondFamily several rows of sharp teeth]]!''
* Bit of a FridgeHorror but all the parents are taken away in the film. What happened to all the toddlers and infants that were left behind while their parents were gone?
