Peppa and George are sister and brother. Their room is not tidy. A yellow toy box is in the room, but toys are not in it. They are everywhere on the floor. Look! A clock is on the floor, too. It's white.

"Come on. Tidy up the room," Dad says. "I can help George and Mom can help Peppa."

"We can have a race (比赛)," Peppa says.

"OK," Dad says. "See who can tidy up first."

Peppa puts four books in the green bookcase. Mom puts some toys into the toy box. Dad puts the clock on the desk and George helps tidy up the room, too.

Whowinsthe race? They all win. Look at the tidy room!
