Team Umizoomi must catch The Troublemakers when they steal the children's lunches. They must hurry back before the troublesome duo reaches their secret picnic spot for their meals.
Intro: Jonathan's Classroom
Team Umizoomi goes to school with Jonathan for the day. He places his backpack in his cubby and his race car lunchbox in the lunch wagon. Bot counts eleven lunchboxes altogether, including Jonathan's.
The TroubleMakers Snatch the Lunches
Everybody sure does love a neat lunch. Unfortunately, more than everyone else includes the Troublemakers, who find them to be tasty and divine. They call for Trouble Truck and load up all of the lunch boxes in the back before leaving the schoolroom.
Jonathan and Team Umizoomi notice all of the lunch boxes were gone and saw the Troublemakers driving off with them. Jonathan and all of his classmates are really upset to have their lunches stolen. Team Umizoomi promises that they'll get the lunch boxes back. However, they have to make it before lunchtime or else the Troublemakers will eat all the lunches. Geo calls UmiCar, and they all go off to get all of the lunches back.
The Stone Trap
The team hooks the lunch wagon to UmiCar, so they can place all of the lunch boxes in when they get them back. They notice the TroubleMakers going up a steep street called Stone Street, because the street is made up of stones. However, the Troublemakers notice the team right behind them and use their Trouble Ray to booby-trap the stones on the street.
The team bounces back down to the ground. They see that the TroubleMakers have booby-trapped all of the stones. The TroubleMakers drive off, but they unknowingly dropped three lunchboxes at the top of Stone Street. But the team can't reach them with all of the booby-traps.
Luckily, Bot's Robot Computer calculated that not all of the stones are booby-trapped. He uses his computer to find the safe stones, while the others follow his path. The safe stones lead up to the top and the dropped lunch boxes. Now they have the first three lunch boxes, but they have to get the remaining eight lunch boxes before lunch occurs.
Fishing for Lunch
Geo uses his Umi-Goggles to find out that the Troublemakers are using a raft to row down Umi River. Team Umizoomi uses the fishing raft to row after them. While Geo and Bot row after them. Milli uses the fishing poles on the raft to hook three of the lunch boxes. The TroubleMakers row to the other side of the river and drive off. The team rows up to the dock and drives after them. Six lunch boxes down, five to go.
The Grassy Maze
Little Trouble really doesn't want Team Umizoomi to get the remaining five lunch boxes. He tries to get Big Trouble to let him drive Trouble Truck instead, but it turns into a tussle for the wheel. The tussle causes four of the five lunch boxes to fall out of the back of their truck. Little Trouble uses his Trouble Ray to make the grass the lunch boxes fell on would grow into a tall grass maze.
The team uses their mighty math powers to find the lunch boxes and make their way to the end of the maze. They get a call from Jonathan, who tells them that it's almost lunchtime. Milli promises him that they'll get the lunch boxes back soon. There's just one lunch box left, which has a race car on it. Hey, that's Jonathan's lunch box!
The Sneaky Snag
Geo finds out that the Troublemakers have gone to their secret picnic spot in the Forest. However, they're up at the top of the cliff, and the Troublemakers are about to eat Jonathan's lunch at the bottom. Geo comes up with a plan to get it back. He'll turn UmiCar into a Umi-Crane and lower Milli down, so she can get Jonathan's lunchbox back.
Milli puts on her Super Harness, and Bot hooks it to the crane. Geo uses the crane to lower Milli down the cliff. Meanwhile, the Troublemakers argue about who's going to open the lunchbox. They argue so much, they don't notice Milli snagging Jonathan's lunchbox and going back up. The Troublemakers smell something funny. It was a skunk, who chases them. The team sees that the Troublemakers being chased and skunked by the skunk. They agree those Troublemakers won't steal anymore lunchboxes. Now that they got all the lunch boxes back, they can get back to the school.
The team went back to school just in time for lunch. All of the happy kids get their lunchboxes from the lunch wagon and head to their lunch tables. The kids all thank them for getting their lunch boxes back. The team joins Jonathan's table to eat their lunches in their lunch boxes too, which Bot stored in his Bot-O-Mat. Geo brought a triangle slice pizza with circle pepperoni, Milli brought a pattern sandwich, and Bot brought number soup. Bot then asks the viewer what their favorite lunch is. The kids and Team Umizoomi all enjoy a great and delicious lunch that is for them and no one else, except for those Troublemakers.
