The Annoyingly Cute Triplets Who Lived Upon the Hill (ACTWLUH) are some kids who were once enemies of the Kids Next Door. They were rich and during the 19th century they stole the cake and refused to share it. Their descendents include The Delightful Kids from Down The Lane and Numbuh 1. One of the triplets may have been Grandfather's mother. They probably act separately. When the KND attacked the Alamode to get the recipe, however, Numbuh 19th Century accidentally set off a bomb in which five thousand operatives were frozen and decomissioned.
