Una excursión loquísima (Leo Luna, 2)

These are the facts: 1. Leo Luna is an alien (yes, that's serious). 2. His spaceship has crashed on Earth. 3. Now he has to go to a school for humans (a drag). And to top it all off… no one, NO ONE, can find out his secret! Today Leo's class is going on a field trip to the Natural History Museum. But it's a complete disaster… and it looks like they're going to discover his identity. What if they catch him this time?! BEING THE WEIRDO IN CLASS HAS NEVER BEEN SO MUCH FUN.
