Yarnbenders is episode 4b of Season 4 of Rocko's Modern Life. When Filburt gets sick, Rocko & Heffer heal him with a mash up of stories about Hansel & Debbie.
During a sunny day, Filburt arrives at Rocko's house to invite Rocko and Heffer in a game of baseball. Rocko goes back inside to get his glove and while Filburt practices on his swing, he gets stuck on his back. Soon, rain begins to pour and Filburt winds up catching a cold. Rocko takes him back inside the house and Filburt tells his friends that his mother used to read to him when he was sick. So Rocko reads The Really Really Big Book of Fairy Tales and reads the Three Little Bears. But he then picks another story when Filburt reminds him that porridge makes him nauseous and comes across a story named Hansel and Gretel (or in Heffer's case, Debbie).
In the story, Hansel (Heffer) and Debbie (Rocko) skip through the woods after attending a circus when they come across a sign that tells the two a shortcut to their house. So they skip through the forest, oblivious to the evil witch (Filburt) behind them. Meanwhile, Hansel and Debbie discover that they are lost and the trail of breath mints have been swallowed by the birds. They come across a house made of healthy snacks. But Heffer interrupts the story and says that the house should be made of pizza instead.
As Rocko and Heffer argue over whether healthy snacks or pizza should be what the house is made of, Filburt decides to have the house made of fish sticks.
Back to the story, Hansel and Debbie attempt to enter the fish stick house and encounter the witch, who invites them outside. The two children are locked inside a cage and the witch feeds them as they are about to be cooked into the pot. Debbie notices a can of Magic Beans on the shelf and Hansel grabs them and attempts to devour them. But Debbie snatches them from Hansel's hand and shows him that they are magic by throwing them on the floor. A beanstalk then sprouts and the two children, still in their cage, are carried away by the stock. As they end up in the sky, the giant grandma (also portrayed by Filburt) carries them with her and sharpens her teeth to get ready to eat the two children. Debbie pulls out a key in her hair and the two children free themselves out of the cage. The giant grandma chases them into the kitchen and corners them. When Hansel shouts out "porridge," the giant grandma becomes nauseous and the children tie her shoelaces together. When they make a run for it, the giant grandma trips over at an attempt to chase after them. Hansel and Debbie jump out of the house in the sky and scream as they fall down.
The next scene then shows Heffer prolonging his scream, which is cut short after an annoyed Rocko shouts out "SHUT UP!"
Back to the story, the two children end up on the ground and come across the witch once again. They run away and take the elevator to wherever they end up at, only for the witch to arbitrarily appear in their presence. When they take the elevator to Cinderella's story, they encounter a fairy (also portrayed by Filburt), who turns Rocko into a prince and Heffer into a princess, calling himself CinderHeffer. The fairy also offers the two a coach and they ride away, only to end up back in the woods, where they once again encounter the witch. The witch offers them a blue apple, which CinderHeffer impulsively bites off of, and a bubbly beverage, which CinderHeffer drinks the whole glass of. When the witch offers a glowing breath mint, CinderHeffer places it on his tongue and turns into a wooden puppet. Rocko and the other animals sadly circle around the puppet, and the witch sneaks back to the broom, attempting to escape, only to get subsequently crushed by numerous of ponderous objects. When Rocko notices the witch's glass slippers sticking out, he takes them and puts it on the feet of CinderHeffer, bring him back to life. The prince and CinderHeffer get married and lived happily ever after.
As Rocko finishes the story, Filburt is now feeling much better and runs out of the house. Rocko and Heffer then sneeze and realize that they had caught Filburt's cold. They are then seen lying in bed sick.
The birds who ate the breath mints do a takeoff on Stan Freberg's soap opera parody, "John...Marsha..."
Filburt: Wait!!! I was gonna make Espresso! This is a most obvious reference to Gene Hackman as Harold the Blind Hermit in Mel Brooks' Young Frankenstein (1974). Hackman ad libbed that line, incidentally.
The following fairy tales/fantasy stories are parodied, in order:
Little Red Riding Hood (at one point, Heffer, as Hansel, comments on the size of Filburt's, as the Granny Giant's teeth)
Cinderella (Filburt, as the fairy godmother makes a potato and a rat grow so Rocko as Prince Charming and Heffer as Cinderella can ride to get to the royal ball, Heffer as Cinderella wears the witch's glass slippers and they make him come back to life.)
