There are three rooms. There's the "Hanging Out Room", the "Practice Room", and the "Weapons Room". The Teletubbies often hang out in the Hanging Out room. That one is a no-brainer. They often brag about their last attacks while here. In the Practice room, they practice their destructive techniques. Such as fist fighting, gun attacks, and bombings. All of their weapons and explosives are kept in the weapons room. They go here to stock up on weapons before they BLOW UP YOUR FACE!
