The PC works like this:
First you have to go on to the tamagotchi website:
https://us.tamagotchifriends.com/dreamtown/. Once your there you must play the dream town game (The link I put takes you directly to the game) You have to play the in order to earn tickets. Once you get enough tickets you most go to the docks where the Music Café is. (I don't know what it's called, but you'll know it when you see it,) Once you get there you'll see the fortune teller (The tamagotchi at the ticket booth) click on the ticket booth. (The ticket booth is only available from the after noon to sunset, I think) Once you get there they will ask you to enter a code from the device. Go to thee door icon and select pc. Then enter the code from you're tamagotchi to you're computer. They will then ask you how many tickets you want to use (It says that the more tickets you use the bigger the surprise, however my experience I didn't really get anything special, just food.
) So after you pick how many tickets you want the computer will give you a log out code. You nee to enter this code in to your tamagotchi to get your surprise. It's really simple to enter it in. Just do the same thing you did when entered your user name. After that confetti will appear on he screen and your surprise will be revealed! (^-^)
