Sick vs Healthy PT 6

Hello! Today's writing prompt is about this picture:

Here are my sick vs healthy sentences! I hope you enjoy them.

Sick sentences:
There was a house on a snail. The snail was big and twisty. It floated in space. There were lots of stars.

Healthy sentences:
Solemnly, a royal castle was perched onto the middle of the snails immense shell. There was all sorts of twists, little ones, medium ones and large ones that pattern the shell. Like a ghost, the snails shell hovered over the surface of the ominous planet. Trillions of luminous stars surrounded the planet with powerful light.
