Team Umizoomi Wiki

Dump Truck is a supporting antagonist in Team Umizoomi. He is the longtime rival of Umi Car but they tend to be friends sometimes.



He first appeared in Race Around Umi City when he intentionally popped Sam's balloon. He even made fun of UmiCar because he was so small. He also cheated by raising the drawbridge, dumping dirt on Team Umizoomi, and dropping soap that made UmiCar slide so much he broke his steering wheel. He and UmiCar raced to the finish line, but UmiCar won. Sam shared his balloons with UmiCar and Team Umizoomi, and UmiCar gave Dump Truck a balloon. He was sorry for being mean and mischevious whilst popping Sam's balloon and laughing at UmiCar and promised to be a team player. His face looks somewhat peculiar.

However, in The Great Shape Race, he was still selfish and a cheater. He wanted the magical dodecahedron for himself. This time, he didn't laugh at UmiCar, but he self-proclaimed himself to his rival. He cheated by not waiting for go, cutting the rope to get over the cliff, dropping glue everywhere, and destroying the car path. UmiCar still won in the end and shared his flying powers, granted by the dodecahedron (twelve sides), with Dump Truck. This time, he was really, really apologetic and regretful for cheating and being selfish.

He also appears in UmiCar's Birthday Present as one of the guests. He was not like he was in the other episodes. He was happy and kind. This is technically fortunate because the episode's events were taken place after that of the next episode.

In Umi Grand Prix!, Dump Truck returns to win the aforementioned race. When Team Umizoomi, UmiCar, and Shark Car come up to Dump Truck, he first tries to stop them with wet cement. When the Team catches up, he tries pooting enough smog to obscure sight. After UmiCar and Shark Car passed him, he threw a major tantrum only to throw wet cement all around him. Later he congratulated them for winning the race by defeating The Troublemakers.



Dump truck was shown to be competitive and Arrogant, during the races he was in. He's also quite mean to any vehicle and also to some people; popping Sam's balloon and making fun of Umicar.

During racing, He's already shown to be a cheater in the race, raising the drawbridge, dumping dirt on Team Umizoomi and also throwing soap bubbles on the road to make Umicar slip and break his steering wheel.

However, Dump truck also has a sensitive-side to himself, when after he lost the race and the great shape race. This could mean Dump truck doesn't really like losing, however in the episode "The Umi grand Prix." Dump truck didn't look sad when he lost, which could mean, he's gotten used to it by now.

However, Dump truck could also sometimes be a liar, as when the end of the episode of "Race around Umi city." He did look happy with Umicar and promised he'd be a fair teammate, but in the episode "The great shape race." His attitude didn't change and was still a selfish cheater. Same goes for the episode "Umi Grand Prix."

However, in the episode "Umicar's birthday present" he was happy and Kind, this means the episode takes place after the last three racing episodes. And this shows that Dump truck is a nice and friendly truck in general.
