El reloj del tiempo (Magicornia, 3)

My name is Lucas, I'm Claudia's cousin, and when I grow up I want to be a great magician! Here, my mother has opened Magicornia, the Bazaar of Amazing Things, and today I'm going to run the shop! Finally, I'll be able to investigate the rarest objects! But wait a minute… What is that strange clock that just arrived? And why does it seem so important? Will you help me find out what it's for?
