How do I upgrade Zoo buildings? What choices are there?
Buildings can be upgraded once you get a certain number of animals at the Zoo, at which point they are marked by a green arrow sign. There are different types of upgrades:
– An extra basket for stock items
– Bonus coins for sold items
– Bonus popularity points for sold items
– Faster sales
Here’s how to upgrade buildings:
1. Go to one of your Zoo buildings and tap the arrow button in the bottom right corner.
2. A window with a list of the upgrades available for this building will pop up. Tap the + button under the icon you’re looking for.
3. Tap the Upgradebutton.
