Bad Export for You: The "Canada Edition" of the show. It added a narrator, shuffled episodes around, and edited the episodes to be more mundane. The "British Edition" takes the badness even further by rearranging and editing it again to remove even more content. This version is aired in the UK, as well as in former British colonies like Australia and New Zealand.
Blooper: The first UK VHS releases state that Pingu was first broadcast in 1991, which is actually the show's UK premiere year. The first episode was broadcast in the show's original network, RTSI in Switzerland, in 1986.
Fan Nickname: Google "Pingu Leopard Seal" and "Pingu Walrus" and see which gets more correct results. A four year old watching the episode for the first time probably wouldn't know what a leopard seal was, but would associate the mustache with a walrus. There are even pages on facebook about the evil walrus, not leopard seal.
Talking to Himself: In the original series, the voice of everyone was done by a VA named Carlo Bonomi, who appeared to be Italian, like Super Mario. Unfortunately his inability to speak English resulted in his dismissal from the revived series, and two actors from London replaced him.
