You need to collect sun points to level up your zoo. ☀️

Here's what you need to do to collect them:
🌼 Get animals. Go to a habitat and tap an available animal to see how many sun points you get for it.
🌼 Install decorations. The amount of sun points you get is shown on its icon.

Fill the progress bar with sun points to increase the amount of coins you get for beating match-3 levels. Doing so will also unlock new expansions and areas.
