Inside the building are various advertisement posters for the I-Cubits. An elevator leads to the top floor, where various monitors are situated to look at various areas of Mixopolis.
At the center of the building is a missile containing the Cubit essence. Rafters are located at the very top of the building, right below the window. The building is able to split in half for the missile to launch.
The I-Cubit building appeared in Mixopolis as a base of command for the Nixels. It was seemingly destroyed when a missile was launched from it. ("Nixel, Nixel, Go Away")
