I know what it is, and I have played it!!!! I know because the games on the entama game center
is the same as the ones open now except for a new game. To see it all you must do is use this password on e-tamago: 4284092 2072392 and go to the game center(it is in the same place on tamatown) and click on the race game. Just choose a character and wath the race.Do anything you want buying also! You can do no damage without my tama!
Hope this helps!!!
