It's winter and many animals in the Park are hibernating. But Oto can't stop himself from being noisy and he wakes them up. Whoops. Now the children and Yoko must find a way to help the animals fall asleep again. They try to put the animals back to bed by creating a Dreamland with clouds, stars and sheep to count. They sing lullabies. In the end they manage to send all the animals back to sleep, a moment before the children themselves fall asleep as well (in Ranger Loops' shed).
