This code gives the Love Potion. The love potion is very important. When your Tamagotchi boy and girl reaches the age of 7, they will need to become good friends before they can have children. Typically this involves connecting several times to build up the friendship up to four happy faces all the way up to four hearts. Sometimes there's simply not enough time to do this. So this is where the Love Potion comes in handy. First you feed this item to one of the adult Tamagotchi and than connect the two Tamagotchi. Select Visit. It should only take once or so and the Love Potion should make your Tamagotchi fall in love. I did not have to use the Love Potion on both of my adults, but if it doesn't work you may want to try that.
