The Troublemakers zapiy
have made a new machine that can make people in any city feel in any mood they desire. They decided to test it on Umi City and by using that machine, not only do they make people sad, they also make Team Umizoomi sad as well, making tears fall from their faces. Can Team Umizoomi save the day before all of the crying becomes a huge flood?
