The Happiness icon is displayed at the bottom as a pink icon with a happy parrot inside. To fill the happiness bar, you'll need to meet all their needs daily and, after a certain amount of time, pamper your baby macaw with some gentle pets.

To pet them, tap the icon to open the petting menu. Once inside the menu, drag your finger across the screen to cuddle your little one. Petting them will instantly boost their happiness, filling up the bar at the top right.
