Pingu Dot Net  was the official Pingu website. On the first page of the entire website, the viewer could select their language by clicking on 1 of the 7 flags surrounding a snowman. The main selections were: UK, USA, Canada, France, Switzerland, Germany and Japan.

Clicking on all the flags except for the United Kingdom and Japan flags would display an intro which shows Pingu rolling into a ball landing, he then walks to the viewer. Looking at his Family he yells a Noot Noot at them, in which the intro focuses on Robby, Pingu's Father, Pingu's Mother, Pinga, and Pingi for a split second. Then focusing on Pingu, he makes a smile with his beak and the intro ends focusing away from him. The intro uses the Küchenchef theme tune used for Season 1 and Season 2, but in a high pitch. As of 2016, all the Pingu websites are currently in maintenance, except the Japanese one, which could mean that Mattel may bring Pingu in the City to the aforementioned countries. As of 2018, all of the Pingu websites (with the exception of the Japanese website) redirect to the Mattel website and have been closed down.

The IP rights to Pingu are currently held by an entity owned by HIT/Mattel named Joker, Inc., which is usually called through its trade name "The Pygos Group" on copyright and trademark notices related to the Pingu property. 

Pingu has received mostly positive reviews. Common Sense Media gave it 4 out of 5 stars, stating: "Parents need to know that this claymation series is funny, endearing, and entertaining. Although it is appropriate for all ages, the plots might be difficult for the youngest viewers to follow". According to a 2008 Slate article, the series is "an international sensation", but still remains obscure among American audiences.
