FOOSH is the onomatopoeia for Winifred's magic scroll in The Underburbs, so FOOSHing just became my shorthand for when someone gets transformed by said scroll. I took some of the input from the sketch of administrative assistant extraordinaire Heather Sanborn. I like the idea of her getting something advantageous to her job since she's not actually wearing a Halloween costume to prompt the scroll's effects. (See Underburbs #1 for a rundown on how the scroll works.) Hopefully, Spider-Heather doesn't overwork herself too much; she might trip over those extra legs!
