The Train and the Monster

A train stopped in the valley, and he was unwilling to go any further. Because there is a mountain monster living in the valley, and the mountain monster is awakened by the screams of children. Trolls love screaming children because they are the most delicious. Shhh—— At this time, you must keep quiet so as not to be discovered by the mountain monster. Purpose: Don't run and make noise in public places
