Gong Heights

Gong Heights, also known as Metebelis I-A in Uku Kivistik's Doctor Who, is a gas planet with breathable air and clouds. The planet is striking a resembelence of Rayman (PSX and PC) level Gong Heights, exactly the same. The planet's atmosphere is a normal Earth's sky, orange with a sun shining in the background. The only land on the planet is clouds and giant musical instruments. The planet's moons are Metebelis II (Axos Earth) and Metebelis III. Their star is Metebelis I, also known as Metebelis Alpha. Unlike Metebelis II and Metebelis III, this planet does not contain any life signs, apart from crashed Daleks and Cybermen who collapsed and rot away 30 decades ago. The moons, Metebelis II and Metebelis III, has living objects on it. On Metebelis II, there are colonized humans fighting against the Axos and on Metebelis III, there are humans living on it.

It is very unlikely that the TARDIS can land on the planet but in the script of the episode in Season 3 of 15, the TARDIS lands in mid-air, kicks the Doctor and his companions out and then takes off. And the Doctor with his companions will spend their time on the planet for entirety of 6 episodes/1 season and 2 episodes.

In the center of the planet, there's iron, as in the form of liquid. The planet has 75 times more iron, gold and diamond, in form of liquid than on Earth as in material/liquid/item.
