As the story begins the ideal user is enjoying the sense of agency that navigation brings, exploring curiously, but open to the suggestion to go to the shed!
At first the user is powerless, then a key appears. If the user doesn't do anything it prompts the user to click on it. When the user clicks, the key moves to the box, turns in the lock, then...
The shed explodes as the box flies open and dark rock-like shapes pour out of it and scatter across the plain.
Before the user can draw breath, the rest of the box collapses and the Thing pops out joyfully shouting...
The Thing is a creature composed of multi-colored, translucent pyramids. It is immediately obessessed with consummating its feelings for the user by teaching the user a dance.
In the picture on the left, the Thing is the blue and yellow thing.
