Snorlax

This Pokemon is very lazy — it just eats and sleeps. As its mass builds, it becomes even lazier. In "Wake Up, Snorlax" Ash and the gang hungrily enter a small village — only to find that there is no food! The river has been dry for weeks and no one knows why. Our gang discovers a giant Snorlax plugging up the water flow, but they can't get it to move. Help from a hermit and his Pokemon whistle saves the day — and lunch too!
