I know that Freddy Krueger fattens up one of his victims in a Nightmare on Elm Street 5: the Dream Child, but I do not know about the comics. I tried looking for this online, and found it referred to on Deviantart in the comics, but no one knows the title. I know someone wrote "A Nightmare on Elm Street 8: Freddy’s Back From The Dead" on Deviantart, it might be part of that story. Did you see this in an actual comic or a comic online?
This may be a print comic or possibly a web-comic, it's Nightmare On Elm Street related and it has Freddy fattening up a woman and also making a reference to the 'squeal like a pig' scene from Deliverance.
