I can’t determine the correct answer from the description alone because the actual spot-the-difference image isn’t included. The text describes the scene but doesn’t reveal which object was changed.

If you upload the image, I’ll identify the exact difference.

For a puzzle post, you can use a placeholder like this (to be verified with the image):

Be sure to confirm the exact difference against the image before publishing.
