Urlic

Urlic was a barren desert planet in the Catorkian Galaxy, Starkey remarked that its air smelled of rotten eggs.

Sometime before 2050, it became the last planet in its galaxy. Due to its endangered status, it was archived by the Ukkans into a Library card. However, it was taken from their archives by Huskian pirates. Eventually the card found it's way to Earth and it was acquired by The Department. As there was a prison over-crowding problem on Earth in 2050, Inspector Thorne decided to turn into a prison colony and just dump prisoners there. He lured Starkey to it in a careers day in Department HQ, when Starkey found it's card he was sucked in and transported to the planet. Darius Pike brought it to the Gryffen House, they need the plinth of the card to bring him back. K9 Mark 2 and his friends tricked Thorne into giving it to them so they could release Starkey then give the card to him, they gave him a (false) pair of goggles which provided immunity to the card and he was transported to the planet. The Ukkan librarian Yssaringintinka was able to return them. (K9TV: Lost Library of Ukko)
