09-5 What's Down the Hall 一不小心

What's Down the Hall Mouse lives in the walls of a tall building. One day, Mouse sees a small ball rolling down the hallway.

He wants to add this ball to his collection. So he chases the ball all the way down the hall.

But they both fall over the edge. All of a sudden, he can't see anything at all.

"Hello?" But he can only hear his own call. Suddenly, he sees a small hole in the wall.

He doesn't stall. He scurries through the wall. On the other side is the biggest surprise of all.

Who knows he lives so close to a toy store in a mall?
