Your mother is way sluttier than the Frankenstein's monster one, in my opinion, though the latter does bring to mind the slutty adult version.
Your mother isn't so bad. I highly doubt your mother would care much when she sees her baby's halloween pictures as compared to any of the other baby ones. For one thing, your mother would definitely be more evil than that. Plus, when it comes down to embarrassing, I would rather be your mother than cotton candy.
