Pingu's Dream (Lost Original Audio)

The Season 1 finale of Pingu, titled Pingu's Dream, in itself could have become a lost episode. It was banned after its original airing in 1990 for the walrus being too frightening for children. It was banned from all the United States after the airing, and was pulled from television in the United Kingdom when it aired in 2003. Later on, it was only released in a couple of DVD/VHS releases containing the first season, and it did air once on PBS Kids Sprout in 2006, saving it from becoming fully lost, though there were some edits made so that the episode was not as frightening to young viewers.

The audio of the walrus terrorizing Pingu was changed for the home video releases. In the original May 12, 1990 airing, when the walrus would pop out and reveal himself to Pingu in the nightmare, it would roar and squeal, instead of laughing in the edited version for the episode.

It is likely that this audio will remain lost, as it only occured in the original 1990 airing.
