Original sentence:
"Eugene Krabs ran past the large spooky ruined, warehouse at the edge of town."
1. Added a comma after "large" to separate the adjectives "large" and "spooky."
2. Added a comma after "spooky" to separate the adjectives "spooky" and "ruined."
3. Removed the comma after "ruined" as it was not needed.
4. Removed the extra comma before "warehouse" for proper punctuation.
5. Capitalization and spelling were already correct in the original sentence.
And if you do all of this, you'll end up with: "Eugene Krabs ran past the large, spooky, ruined warehouse at the edge of town."
