I had lobstraganda at first but amended to lobstroganda due to the quoted sources being lobstrosities.
Well, I wasn’t 100% sure of how King had spelled it so I searched duck duck go for “ded-a-chek” and the Dark Tower Wiki entry for Lobstrosities topped the list. Sound out of deference to the source material: lobstroganda.
Thanks for coming to my TED talk.
oi look at the brain on this one!
