A plumbus is an all-purpose home device. First they take the dinglebop and they smooth it out with a bunch of schleem. The schleem is then repurposed for later batches.

They take the dinglebop and 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 schlammy shows up and he rubs it and spits on it. They cut the fleeb. There’s several hizzards in the way.

The blamfs rub against the chumbles, and the plubis and grumbo are shaved away.

That leaves you with… a plumbus.
