Milli, Geo and Bot are visiting their friend Jonathan at school when the TroubleMakers show up and swipe all the kids' lunchboxes! Team Umizoomi hops into UmiCar and the chase is on to get them back before lunchtime. The TroubleMakers have got quite an appetite, as they lead the Team in hot pursuit through booby-trapped avenues, down a winding river, and navigating through a giant grass maze. Can Team Umizoomi retrieve all eleven lunchboxes before the Troublemakers gobble them up?
