sorry i got mixed up between the old japanese commercial and the tamagotchi connection one.the old japanese commercial had the theme song to the tamagotchi cartoon.here is the link to a reveiw of the cartoon vhs tape.

the website should also be in the hall of shame cause in the message board people are so crule to their tamas.here is one example:a boy see's his little 5 year old sister play with her tama(they were at a lake).his little sister shows him her tama as an adult.then hthe boy says i want to show you a rare fish at the lake.the girl says okay. the boy snatches his little sisters tamagotchi and tosses it in the lake.the little girl cries and says she will tell on his mom.the boy says go ahead see if i care that thing was a peice of junk anyway.the girl tells on his mom and the boy get groounded.but the boy continues to make the girls life missarable.and he dosn't care about what he does...
