Teletubbies

They are these weird characters which we won´t never know what´s their sex.
They live in a kind of Wonderland where there are fool things like rabbits that never died, a sun with a baby´s head who is always smiling and a vacun cleaner.
They have a house in the middle of a mountain where there are some speakers which say them what they must do, and they aren´t too clever and obey it.
All of them have a TV, but isn´t a HD TV, and play a boring video twice. Their belly shine when their TV is on, so they seem Terminator.
They have a very big and stranger antennas on their head but it doesn´t work properly because their TV has a very bad quality.
