Producers Anna Goldfield and Marc Sanchez are in the Brains On Zoo and oh no! The animals are loose! Anna and Marc will have to use their animal calls to bring them all back. But first, they'll play a game of Impression Sounds to see if their animal calls are good enough. Impression Sounds is like Mystery Sounds, but instead of listening to a recording of a sound, they’ll have to make animal sounds with their mouths. The other person will then guess what animal they are trying to imitate! Get ready for a barnyard bonanza.
