Ursino Six
From Tardis Wiki, the free Doctor Who reference
Ursino Six - also known as Planet of the Bears - was a planet whose inhabitants were stuffed bears, who were reality-engineers. Teddy Sparkles hailed from Urisno Six, and after Missy kidnapped him, he often thought that he would never return home. (PROSE: Teddy Sparkles Must Die!) Panda, a living stuffed panda bear, had previously speculated that he hailed from a "planet of pandas" when he was arguing with Iris Wildthyme about his origins. (PROSE: Enter Wildthyme)
