To start interacting with the game, click the large turkey balloon outside your zoo. This will bring up the screen shown above that shows you your progress on blowing up a balloon. Currently, there are two animals available to receive through the parade, a Autumn Hound Dog and a Thanksgiving Pilgrim, but new animals will be available every 3 days.
Second, you need to collect items from feeding Thanksgiving treats to your animals. This means that when you click the hearts on your zoo enclosures, you should always feed the Thanksgiving treats. This will give you the chance of getting Maize, which you need five of for the first animal and you can collect five per day.
Third, you need to collect Drums which you and friends can share to your feed one time per day. For each feed, 10 friends can collect a drum. You can also purchase all of these items for 1 WLP each.
After you have collected all the materials, you still need friends in order to blow up your balloon. 5 friends have to click on your wall post to help you blow it up to allow it to be placed on your zoo. You also get the animals itself, and you can do each one of these over and over again to get as many animals as you can get. Note: you will only get one balloon per animal unlocked so while you may have 6 hounds you will only get 1 hound balloon.
Complete this each day and you will unlock a ton of different animals including a turkey and some other animals which we cannot determine at this time. We'll be sure to update you when new animals are available to acquire through the Thanksgiving Parade!
