Back to Backspace and Pillywags' Mansion

Patti and her coworkers Herschel and Sweatpants, who are brothers, live and work in Backspace, a virtual reality where "deletions"—rejected ideas—are sent. Their boss Yaga tells Patti to look for incoming rejections. At the headquarters of a newspaper company, its CEO rejects a design proposal for a cartoon man named Mustacki, sending the file to the trash and emptying it. After Mustacki is sent to Backspace, Patti calls Yaga for a hovercraft so they can give him a guided tour. Patti and her workers explain that there are three types of deletions: "good-bad" ones, which are sent back; "lousy-bad" ones, which are counseled and repaired; and "evil-bad" ones, which are tortured and shredded. Patti becomes distracted by a group of singing cubes, called soundcubes, and leaves the brothers to explain that "Krampses" are a group of "evil-bad" deletions whom are difficult to purge. Herschel tells that Ranklin, leader of the Krampses, was captured by Sweatpants, but Sweatpants suggests that it was actually Herschel who did so.

Patti collects the soundcubes for herself and then returns to find Mustacki missing. Ranklin had appeared in her absence and is holding Mustacki hostage at the shredder. Patti and the brothers tell Ranklin that Mustacki is already dead, and Mustacki spits out some gummy worms to demonstrate this. Falling for the trick, Ranklin kicks Mustacki away, only to be laughed at for his gullibility. Before escaping to the real world, Ranklin taunts Patti, by suggesting that the others should ask her about how she got sent to Backspace in the first place. When her coworkers and Mustacki ask what they should do next, Patti shrugs it off, tells them that she has to go, and suggests that Mustacki get a job at Backspace. At her abode, Patti houses her soundcubes in a container in such a way that they fit together as a rectangle. On her laptop, she records a song pondering her existence in Backspace.

Pillywags' Mansion uses puppetry and centers upon a fictional variety show within the series, titled The Pillywags Show. The titular Master Pillywags hosts the variety show in his basement, with the help of his servants, Screen (a projection screen with eyes and a mouth) and Greg (a goblinesque creature). In the pilot, Pillywags interviews a pair of inanimate dolls propped up on a shelf before performing a song about love. He then invites a guest onto the set, his neighbor Professor Steve, who has been captured by Pillywags pet monster and is enclosed in its mouth. When asked by Pillywags why his monster chose to swallow him, Steve posits that, due to his small stature, he was mistaken for prey. This brings Pillywags to the topic of size, and, before airing an animated segment on the topic of it, he asks the viewer the question, "is it better to be big or small?" After the cartoon, Pillywags answers the question saying that it is better to be big. As the credits roll, Screen and Greg "take five" before preparing themselves for the next show.
