Kayla’s fun at the water playground comes to an abrupt end when the elephant water sprinkler stops working! To help Kayla, Team Umizoomi needs to know how water gets to Umi City. “How Does It Work” shows us the process and now it’s up to the Team to figure out where the problem is and fix it fast. Our tiny action heroes build a super submarine and zoom through the under ground water system to help get the water sprinkler flowing again!
