Hi there Tgirlk421,
If you search through the Tamagotchi codes fourms you should be able to find bonding item codes enter 1 or more of the bonding item codes and then go to your items or rares and you should see the items select one of the bonding items and keep pressing button b (Middle Button) until you have played with the item:
100 times if it is a 0.1 bonding item
34 times if it is a 0.3 bonding item
Hope I helped if you need any help PM me!
