 Inside the binder is a starter pack of "account book" (kakeibo) pages used to track the user's spending of "gotchi points", the currency used in all Tamagotchi toys.Initially released with a pink body and orange stylus, a later version released around the same time as the uratama features a blue body and green stylus, new screen background, and new binder cover (although with the same black-pixel LCD and programming).The kakeibo is not really a virtual pet like the other portable tamagotchi, but more of a tool to assist with caring for them.
