On the left side of the sky there was planet Shadok. It didn't have a particular shape, or rather... it changed shape.
On the right side of the sky there was planet Gibi. It was completely flat and tilted from one side to another.
In the middle there was the Earth - round and moving. Apparently there was nothing on the Earth.
On the planet Gibi lived the Gibis.
When there were too many of them on one side of the planet, the planet tilted and the Gibis were sliding and falling off. Which was quite embarrassing, especially for the Gibis.
On the planet Shadok lived 2 types of Shadoks:
- Shadoks with legs on the bottom, living on the top of the planet
- Shadoks with legs on the top, living on the bottom of the planet - responsible for supporting the planet
Because the planet Shadok kept changing its shape, the Shadoks kept falling off. Which was quite embarrassing, especially for the Shadoks.
Eventually the Shadoks and the Gibis decided, that they had enough of living on their uncomfy planets and made up their mind to go to Earth, which seemed a much better option.
