Crystals are small, heart-shaped pink gems and represent the game's most valuable currency. They are used to purchase special care items for your baby macaw, buy unique outfits and decorations, or skip wait times. You can earn crystals by completing daily quests, extra quests, reaching every 10th level of your little one's Trust level, watching TV, ranking in the top 5 on the daily Breeder minigame leaderboards, or purchasing them directly in the shop.
