The penthouse is in a sense a large trophy room containing stuffed animals Dexter has presumably hunted, the skeleton of a whale he is said to have harpooned himself and a laser-guarded room full of medieval style weapons and a vial of U'wa Tribe Poison. There is also a display room with a mechanized miniature model of Dexter Industries and a number of weapons, including katanas, and also decorations such as old coins and broken antique six shooters. In one of the rooms, there is a panic room hidden behind a fake wall. The penthouse also houses Lenny Dexter's room, which at the time of the mission is empty and guarded since Lenny was left in the desert.
