It was lunchtime Mabel ran to the lunch room with her lunch box. When she looked inside, she didn't have her favorite snack. The rest of her favorite foods were there, so she ate them, and she decided to take the snack back home. It was apparently a mistake. Little Mabel was so bothered by not having her favorite snack that she could hardly concentrate the rest of the afternoon. She left her lunch box and went to get it out of the classroom. When she returned to go out, she went out of the wrong exit. Little Mabel discovered some scenery she had never seen before and decided to explore it. She was, after all, upset that she didn't have her favorite snack, so she decided not to go home. The entire neighborhood turned up to help find her. Ben Jr. searched the neighborhoods and finally found her in a park by the school. When they returned home, the search party turned into a welcome party for the new neighbors.
