The Insane Knife Loving Quadruplets Hidden In The Mountain are the Filipino counterparts to the Delightful Children From Down the Lane and the Interesting Twins From Beneath The Mountain. They are four siblings living in a house stationed beneath Mount Apo, and have a strange affinity with knives, er, fake ones, because they aren't allowed by their parents to use real ones. They are also a bit wacko.

They appear in KND Operation: DELIGHTFUL as minor villains.
