The Cat in the Hat (1971)

After the Cat makes his entrance and fools around a bit, the Fish requests that he leave. He does so, but then comes back in, claiming that his "moss-covered three-handled family grudunza" has been stolen, and he accuses the Fish, who is given the name Karlos K. Krinkelbein in the special. The Cat sings a ballad about the loss of his treasured keepsake and then tries to describe it to the kids, even though they don't understand what he's talking about.
