First, they take the dinglepop and they smooth it out with a bunch of schleem. The schleem is then repurposed for later batches. They take the dinglebop and they push it through the grumbo, where the fleeb is rubbed against it. It's important that the fleeb is rubbed, because the fleeb has all of the fleeb juice. Then a Schlameeh shows up, and he rubs it, and spits on it. They cut the fleeb. There are several hizzards in the way. The blamphs rub against the chumbles, and the klubus and grumbo are shaved away. That leaves you with a regular old plumbus!
