Facts
The Bagels and Locktopus Pun
The episode features a security company called "Bagels and Locks," a clever play on the popular breakfast combination of bagels and lox (smoked salmon). The system's enforcer is the Bagels and Locktopus, a Muppet with many tentacles. It chases Chris whenever a wrong button is pressed. To operate this complex creature, four puppeteers were needed: Martin P. Robinson did the head and voice, while Stephanie D'Abruzzo, Liz Hara, and Austin M. Costello manipulated the various tentacles.
Nick Jonas's Shape Premiere
Pop star Nick Jonas will be stopping by to perform the song "Check That Shape" with Cookie Monster, Bert, and the Count. This was his first time officially being on the show since 2016, but he'd been with the Muppets before. He performed at a Sesame Workshop USO event for military families back in 2011. Bill Sherman and Joey Mazzarino wrote the song to teach people the difference between a pentagon and an octagon by dancing to it.
Catching Up with Fur Parody
The "Cookie's Crumby Pictures" segment is a parody of The Hunger Games: Catching Fire is called Catching Fire. Cookie Monster stars as "Cookieness Evereat," a role that lets him show off his heroic side with a bow and arrow. The segment features teammates like Finicky (Finnick), Wired (Beetee), and Pita—who is literally a piece of pita bread. Instead of a life-or-death struggle, the characters have to solve food-based patterns to win the games.
Instruction Manual Comedy
There's a running gag about Grover's manuals, and they're getting more and more useless. To open the three separate gates, he has to consult two different volumes of the "Bagels and Locks" guide. It's a great tool for teaching comparatives and superlatives (like finding the biggest circle or the triangle that doesn't look like the others). The "Locktopus" chasing Chris at the end because he "likes to work overtime" was an unscripted ad-lib that the producers kept in the final cut.
Security Feed Tech
To update the show for its 2016 HBO debut, the producers added a subplot where Chris monitors the store via a security camera feed on his phone. This meant that the audience could see Cookie Monster's progress inside Hooper's Store as it happened, while the characters were stuck outside. It's one of the few episodes where the "Fourth Wall" is used to show a split-screen view of the interior and exterior of a single building.
Pentagon Power
This episode focuses a lot on the Pentagon, which is a shape that most toddlers have a harder time identifying than squares or circles. The show uses high-stakes physical comedy to help kids memorize the five-sided shape. You'll notice that Abby and Elmo have to count the sides out loud, showing the viewer how to solve the problem.
Karate Master Red-Edited
The "Elmo the Musical" segment, "Karate Master," was specially edited for this broadcast to highlight shapes. In the story, Elmo has to stop a villain named The Ooze from destroying the geometric foundations of a town. This segment was originally produced in a longer format but was shortened to fit the new 30-minute Season 46 runtime, ensuring the episode stayed focused on its primary mathematical theme.
The Birthday Cake Prop
The cake Elmo and Abby make for Alan is decorated with real cookies. While they were filming, the prop department had to have extra cakes ready because the studio lights were so hot they started melting the icing during the long "lockdown" scenes. Also, we had to use hidden toothpicks to hold the cookies on the cake in place so they wouldn't fall off when Cookie Monster tried to "eat" them.
Educational Context & Viewer Guide
Primary Lesson: Geometry (Shape Identification) and Comparative Logic
Pedagogical goal: Reinforce identifying basic shapes (square, circle, triangle, pentagon) and complex shapes, too, while developing critical thinking skills by comparing sizes and spotting "the odd one out."
Parental Note: Grover's turned Hooper's Store into a high-tech fortress to keep the "birthday cake" safe from Cookie Monster! To get inside, Elmo and Abby have to solve shape puzzles. This episode is a great way to turn "Geometry" into a game. You can play a similar game at home by putting a "secret treat" in a box and telling your child they have to find a specific shape in the room (like a rectangular book or a circular plate) to "unlock" the prize.
Expert Take: This episode is all about visual discrimination and spatial reasoning. The challenges go from simple identification (a square) to more complex attributes, like counting sides (a five-sided pentagon) and identifying size differences (the largest circle). The last puzzle is all about finding the triangle that "doesn't look like the others." This introduces the idea of non-standard shapes and shows kids that a triangle is defined by its three sides and angles, no matter how it's oriented or how big or small it is.
Cold Open
Elmo starts the day out by meeting a bunch of "living" shapes. This introduction is a blast and gets the creative juices flowing right away. Your child is invited to see the world differently by seeing shapes as characters with their own personalities.
The Main Street Story
Elmo and Abby try to protect Alan's birthday cake from Cookie Monster. They use a new "Bagels and Locks" security system that Grover created. The mission becomes a series of logic puzzles when the store is locked behind several security gates. To stop the alarms and save Chris from a "Locktopus," the team has to find specific shapes. They have to identify a five-sided pentagon, find the largest red circle, and pick out a unique triangle. This story is a perfect example of geometry and critical thinking. Your child will learn to look for attributes like side counts and relative size. Elmo and Abby show that seeking information and working together are superpowers when a birthday cake is on the line.
Cookie's Crumby Pictures: The Hunger Games
Cookie-ness Evereat and her team have to complete complex food patterns to win the games. This parody is a great resource for developing early math skills, especially pattern recognition. When preschoolers watch characters figure out what comes next in a series, they develop the logic needed for advanced problem-solving. It's a good reminder that paying attention to the little things can really help you reach your goals and make sure things go smoothly.
Check That Shape
Nick Jonas joins Cookie Monster, Bert, and the Count for a soulful performance. The lyrics are catchy, and they encourage kids to look for circles, squares, and triangles in the world around them. Making a geometry lesson into a pop song is a great way to boost young learners' self-esteem. Finding "four equal sides" or "no corners at all" feels like a major accomplishment. This segment shows that everyone can appreciate the math behind our neighborhood.
Elmo the Musical: Karate Master
Mighty Elmo uses his karate skills to defend a town's shapes from a mysterious being known as "The Ooze." This segment is all about gross motor development and creative expression, as Elmo physically protects the squares and circles. It's all about being aware of your surroundings, but with a twist: it also focuses on your social and emotional growth. By encouraging toddlers to stand up for what's right, Elmo shows them the value of the structure and beauty of the physical world.
Shapes and Kindness
The episode ends with a focus on observation and friendship. The street story ends with a "messy" surprise for Alan, but the outro brings things back to a more personal level. Cookie Monster and Rosita are practicing their moves—fast and slow. This gets you moving and helps you understand tempo after you've done the mental work of solving puzzles. These stories balance academic lessons in visual discrimination with the social importance of celebrating a friend. Whether it's spotting a pentagon or sharing a cake, paying attention to patterns and people makes the neighborhood a better place.
