Mine too, but only with the ninja dude and my whale, oh and this flower I had once. All the others didn't watch TV. I think it is because it doesn't have that quality.
I've only had one of mine watch tv that I've noticed...
You can't make your tama watch tv, it's just a random animation like "kissing" the screen or brushing teeth or taking a bath... your tama will just do it when it wants like a screen saver
hysterical_oliver you're right. The old timers snack is coffe, althought while iv'e had my itchigotchi and maskitchi watch TV, I have never caught an old timer doing an action.
