They do need the TV to unwind from work, you could try picking them up when they are watching TV too often and praising other actions more often (praise 2 times) or praise them with candies and fruit when you can! Salty candies and the red glove will both make them sad, but if you do want to use them just make them feel better by praising them when they are good.

I don't really like those heads either, but each one of them would grow on me if they did appear in my family.
