Your tama was yawning. If it was nearing it's bed-time (up to 30mins before the time it goes to sleep) you can go to the lights out icon and put your tama to bed early if you have seen it yawning.
Tamas normally turn slightly sideways and yawn. If you don't have a Mimitchi, perhaps yours looks slightly different when yawning - maybe yours turns sideways more?
Tamas don't smoke
Some ppl thought they were smoking when they were brushing their teeth too. So if it is not yawning, perhaps yours was brushing its teeth (although they usually face you on the screen and it is a close up...)
Just think about it; Do you think BanDai would be allowed to sell a toy to millions of children across the world that smoked...?
Every government would lobby to shut them down because parents would be complaining about tamas and asking for them to be banned!
yeah mine was too i was like what the crud but u know if u think your tama is drinking and smoking p.m. me and i will tell u because my dad told me what was because he works at bandi so i will only tell u by p.m.
[SIZE=8pt]I think mine was smoking. I was watching tv and then it beeped and i picked it up and it was facing the opposite direction (so i could only see its back). Smoke was coming from it and the attention icon was lit up. I praised it and it stoped.[/SIZE]
