The Pencil Bomb!
Here’s an authentic North Korean children’s cartoon. It’s in Korean, but you can follow the basic storyline pretty easily without even knowing a single word of Korean. The story is of a little child who falls asleep while doing his math homework and dreams that his pencil and protractor have turned into artillery guns, which he uses to blow up the evil US (I kid you not) invaders. He then wakes up and realizes the greatness and usefulness of math and spreads the gospel to his friends.
