Very important house is an animated pilot created by Jhonen Vasquez (Creator of Invader Zim) and Jenny Goldberg (Character design for Star VS the Forces of Evil and Rick & Morty) in 2016 for Disney XD. Disney XD ultimately did not pick up the pilot and only a few clips have surfaced ever since.
After Jhonen finished work on Randy Cunningham: 9th Grade Ninja and Jenny finished on Star VS the Forces of Evil the two started developing a pitch for an animated series on Disney XD. The pilot was in development for four years and was rejected in 2016. Jhonen stated in a now deleted blog post "Very important house didn't gel with the current direction of Disney XD.
