One misty morning, a curious speckled egg rolls into your house through the pet door, its shell gleaming with a magical sheen. You find the egg when you return from your jog, resting atop your cozy couch. Puzzled, you approach cautiously, realizing it's no ordinary egg; it's a mystical cat spirit. It seems interested in your collection of rubber balls, especially the bouncy one with catnip inside. You try to gently place it near the egg to see if the spirit will hatch into a friendly companion.
