One morning as Lucy and Zach watch their mom do yoga, they decide they should teach a yoga class for all of their friends! The siblings find a studio space in their building’s basement, set up lots of soothing decorations—potted plants borrowed from the lobby—and put down the “yoga mats” (really door mats) they found all over the building. Then it’s time to begin! Zach and Lucy don’t really know how to do yoga, but from what they’ve seen, it involves pretending to be lots of different animals…right?
