Que Horrifico's pan flute

Que Horrifico's pan flute was a flute played by Que Horrifico at night to warn the elementary children to put on their fake spookified fangs and fake spookified hair to terrify middle school kids, high school kids, and adults. The pan flute was mistakenly destroyed by the Ninja in The End?: Counterpart Nibiru.
== History ==
=== Scooby-Doo! Mystery Incorporated ===
==== The Song of Mystery ====
Que Horrifico used a pan flute (presumably the one in Luis de Potrillo's office) to "spookify" kids at night. When Mystery Incorporated saw the flute in Dr. Portillo's office, they thought he was the villain. The Ninja later then caught him and Que Horrifico was revealed as Fred's child prodigy, Mary Anne Gleardan. After Mary Anne went to prison, the flute was probably destroyed or returned to where it came from.
=== The End?: Counterpart Nibiru ===
The pan flute was mistakenly destroyed by the Ninja when the Ninja mistakenly thought Mary Anne Gleardan escaped from prison. They destroyed the pan flute because they did not want to continue the actions of people getting spookified. Que Horrifico, unmasked to be Colten Potter, the leader of the Ninja, was outraged that the pan flute was destroyed, but the pan flute was just a projection of the Sacred Flute. The Ninja later fixed the Sacred Flute to make it look exactly like Que Horrifico's flute, and Colten started using it to "spookify children."
