The children had known their whole lives they were missing one. As the three girls and two boys played in the sand, climbed the mountains, and explored the world around them, they could feel a small void that was always there. The one thing that could even partly fill that void was their eternally brave, forever strong mother. Then one day, she wasn't strong. She was crying.
She hadn't done anything different, just been reading her paper. Then she broke down. When she went to her room to get it all out, she had left the paper behind. They swarmed it. There they saw him; a little purple dragon on the front page of the big newspaper. It was decided without a word. That was the missing piece. The one thing that made their mother weak and their world incomplete. The one thing they needed back. So without a word they packed their rations, wrote their goodbye notes, and followed behind the two oldest that had already sprouted their wings. They were heading to Canterlot. It was time to bring bubby home.
