What Is The Code On The Back Of The Moshi Monsters Card?

I think its like a mopod but it has a diffrent item with it. If you don't know what a mopod is it is a phone charm that you can have in poppet furi luvi katsuma divalio or Zommer.it flashes and turns around when your phone rings. It has a code that on the third box on MOSHI MONSTERS SIGN IN you type the code in and when you log on it gives you an item that you can't get anywere else! WOW! Hope this answers your question!
