The sky changes color and there are earthquakes. People realize that the snake eating the pie was the first step in a series of events that will either save or destroy their world.

In a ghost story, the ghost in a pie - eating scene might represent an unfulfilled desire. Perhaps the ghost used to love eating pies when alive and now is drawn to the scene out of envy or longing. For example, if a poor person died without ever having enough pies, their ghost might appear during a pie - eating celebration of the rich. It's a way of showing the contrast between the living's indulgence and the dead's lack when they were alive. Also, it could be a warning. If the pies were made in an unethical way, like stealing ingredients, the ghost could be there to punish those who are eating them.
The sudden appearance of the ghost. Imagine you're happily eating a pie, and then all of a sudden, a ghost just pops up out of nowhere. It's completely unexpected and can send shivers down your spine.
