Sloth is a sloooooow creature. She's supposed to be going to the Zzzzzoo, but is mistakenly delivered to the ZOOM! She wants to make friends in her new home, but it seems like all the animals here are always busy, late, and in a rush. Finally, the sloth meets someone more to her speed: a tiny snail who invites the sloth down for a cup of tea. The friendship of these two animals is surprising and delightful enough to stop all the other animals in their tracks. And as day became night, and night became day, the animals at the ZOOM! slowed down... just long enough, that is, to all become fast friends.
