S1·E24 Batty for Bats

Sally and Nick are playing a game of blindfolded tags but can't seem to find each other. Luckily, the Cat has a friend who is always able to find his way in the dark. He takes them to meet Zapata, a bat who teaches the kids about animal echolocation. Now that Nick and Sally know how to listen to find their way, the blindfold tag has become a lot more fun as expected.
