Apalapucia
From Tardis Wiki, the free Doctor Who reference
Apalapucia was a fabulously beautiful planet, home to soaring spires, sunsets, and mirrored mountains. It was home to the Apalapucians, who had a Binary vascular system.
According to the Doctor, it was voted the #2 destination for the discerning intergalactic traveller. (DW:The Girl Who Waited)
