Mecha Builders (also known as Sesame Street: Mecha Builders) is an American animated children's television series and a spin-off of Sesame Street that began production in May 2020.[1] The series is produced by Sesame Workshop and animated by Guru Studio.[1][2]
The project was announced in October 2019.[3] Visual development was started remotely, due to the COVID-19 pandemic. The series intended to add 80 staff as it entered production.[2]
The first of the two stories comprising the first episode was released on April 26, 2022, on the Sesame Street YouTube channel.[4] The series premiered on May 9, 2022, on Cartoon Network, within its Cartoonito pre-school block.[5] The series was later available on the streaming service Max.[5]
Premise
The series focuses on "mecha" versions of three legacy characters: Mecha Abby Cadabby, Mecha Elmo, and Mecha Cookie Monster, all reimagined as mechanical beings with the power to enlarge to giant size in addition to unique built-in tools and gadgets. The trio usually solve a problem using a three-step formula: plan, test, and solve. Later episodes would add a fourth main cast member in the form of Elmo's pet dog Tango.
Characters
Main
Mecha Abby Cadabby (voiced by Leslie Carrara-Rudolph) is one of the three Mecha Builders. Mecha Abby is the sole female of the main trio, and acts as the group's leader. Her gadgets include jet boosters in her wings, a flying hologram generator used to outline their plans, and she has the ability to stretch her arms to great lengths in order to reach faraway objects. She represents the planning aspect of the show's problem-solving formula.
Mecha Elmo (voiced by Ryan Dillon) is one of the three Mecha Builders. Mecha Elmo has high technical powers and is able to assemble many of the devices the team needs (often with some help). His gadgets include wheels in his feet, a safety helmet and visor, and his forearms have the ability to morph his hands into any tool needed for the job, though he typically has to try more than once to get the correct tool. He represents the testing aspect of the show's problem-solving formula.
Mecha Cookie Monster (voiced by David Rudman) is one of the three Mecha Builders. Mecha Cookie Monster is typically excited when it comes to food and while good-hearted tends to be both dimwitted and skeptical. His gadgets include springs in his feet, the ability to see things to identify, search, or scope out a situation (dubbed the "Goggly Vision"), and his right hand can morph into a large hammerhead (dubbed the "Handy Hammer Hand"), though both hands can also merge into a large rolling drum. He represents the solving aspect of the show's problem-solving formula. After a Mecha Builder shrinks (going "Mecha Tiny") or enlarges (going "Mecha Giant"), Mecha Cookie Monster's chest badge also displays the Cookie Clock, a timer that shows how much time the team has left before they return to normal size.
Mecha Tango (voiced by Leslie Carrara-Rudolph) is a fourth Mecha Builder, and Mecha Elmo's pet dog. Energetic and unable to communicate outside of dog noises, her abilities include "super-hearing", "super-sniffing" and her "Turbo Tail", in which her tail spins rapidly to allow her to fly.
When the Mechas notice a giant pie floating above Pretty Big City, they slice it up to share with all their friends. After the last slice is gone, the team learns that the pie was sent by some friendly aliens to stop an asteroid! Now it’s up to the Mechas to find something else to catch the asteroid.
A quartet of singing stone heads are ready to perform at Big Old Boulder Museum, but they can’t stop sneezing. The Mechas have to go “Mecha Tiny” to figure out what’s causing the sneezing, and work together to solve the problem before the concert.
The Mechas arrive on the scene to help a park ranger stuck at the bottom of a crevice. The problem multiplies when Mecha Abby gets stuck on a tree branch trying to reach him. The Mechas need to find a way to lift heavy things so they can free Abby from the tree and lift the ranger out.
The Mechas’ friend, Zee, is ready to launch his rocket into space, but a launchpad malfunction sends the rocket flying off to the farm instead. Once the Mechas get the rocket back to Zee’s launchpad, they need to figure out how to point it back up toward the sky in time for liftoff.
Berta is taking a picture with the Big Old Boulder for the city’s museum, but she needs the Mechas' help when the boulder starts rolling down a hill. The Mechas then work together to get the rock back up the hill and to keep it there.
It’s Food Day in Pretty Big City, and the city is celebrating by unveiling a banana split statue! But when the statue is revealed, the banana atop the banana split statue is not squashed. The Mechas need to fix it quickly before everyone’s ice cream melts.
The magnet crane at the construction site is switched on by mistake, sucking up all the metal in the area, including Mecha Cookie and Mecha Abby. The Mechas learn about magnetism as they figure out how Mecha Elmo can stop the pull of the magnet before anything or anyone else gets trapped. Mecha Elmo then gets stuck to the magnet.
Marwyn is waiting for an egg delivery at the Treetop Woods Train Station. When the engineer tries to stop the train, the brake lever snaps. The Mechas try different ways to stop the train without breaking any of Marwyn’s eggs.
Hero Celebration Day is coming to an end; the big finale is a slideshow of the everyday heroes of Pretty Big City. When the screen rips during the event, the Mechas need to find something flat and opaque to show off the photos and celebrate the city’s heroes properly.
The people of Pretty Big City are cooling off on a hot day with an ice slide in the park, but the situation gets slippery when the ice slide starts melting. The Mechas hunt for something to slow down the melting process and protect their friends’ summer fun.
