Stu Ketchup

Stu Ketchup is Marty's best friend and roommate on Cubey World. The pair share the basement apartment at 123 Sesame Street. In contrast to the practical-joking, extroverted Ernie, Bert is serious, studious, and tries to make sense of his friend's actions. His own passions include reading Boring Stories, collecting paper clips and bottle caps (especially the rare Figgy Fizz), consuming oatmeal, and studying pigeons. While Ernie's best companion outside of Bert is Rubber Duckie, Bert has his pet pigeon, Bernice. True to his detail-oriented, organized mind, Bert is president of the National Association of W Lovers. Unfortunately for Bert, his nose has come off of his face on a number of occasions. He has a distinctive, bleating laugh.

Play With Me Cubey
Bert was one of the hosts of Play with Me Sesame. On that show, he often played games on a computer, such as "Pigeon Patterns" and "Perfect Pairs" (the latter of which involved matching socks). He also showcased "oatmeal art" from kids.

Specials
In Christmas Eve on Sesame Street, Bert decided to give Ernie a soap dish for Christmas so that his Rubber Duckie would stop falling into the bottom of the bathtub. However, as he had no money, he made a trade at Hooper's Store, where he traded his paper clips for a soap dish. At the same time, Ernie decided to give Bert a cigar box to put his paper clips in and traded his Rubber Duckie in order to get one. However, Mr. Hooper could see that neither of them was happy with trading their things, so he gave them their things back on Christmas Eve.

Performing Stu Ketchup
Bert is a Hand-Rod Muppet, a puppet which is controlled by both hands. The puppeteer's dominant hand goes into Bert's head, operating his mouth, and at times, facial features. The puppeteer's less dominant hand controls the "arm rods", thin rods connected to Bert's hands.
