Our heroes are curious about the origins (and sleep habits) of Principal Oak’s Komala. After telling the students how they met, Samson shows off Komala’s impressive skill at battling in its sleep! They get another lesson in sleep when Jigglypuff shows up at the Pokémon School! As always, its song sends everyone to sleep, and they wake with angry scribbles on their faces…everyone except Komala. Jigglypuff keeps coming back and gets angrier and angrier when Komala won’t wake up and listen. That gives Samson an idea … when Jigglypuff returns, Komala uses the Sleep Song and makes Jigglypuff fall asleep, and Komala doodles on its face! Rather than being grumpy when it wakes up, Jigglypuff seems to think this is hilarious and Komala has a new friend! (Source: Wikipedia)
